Q.Match the principles with the instances:

The question asks you to match four principles of boundary delimitation with four real-world instances. Let us go through each principle and see which instance fits best.

First, mapping boundaries on religious grounds. This refers to a partition where religion was the primary basis for drawing the line. The most direct example is the creation of Pakistan and Bangladesh (formerly East Pakistan) as separate from India, based on Muslim-majority areas.

Second, mapping boundaries on grounds of different languages. This is the principle of linguistic states. The division of India and Pakistan in 1947 was not primarily linguistic — it was religious. However, the separation of Himachal Pradesh and Uttarakhand was based on linguistic and cultural identity (Pahari-speaking regions), so that pair fits here.

Third, demarcating boundaries within a country by geographical zones. This means using natural features like rivers, mountains, or forests. Jharkhand and Chhattisgarh were carved out largely on the basis of tribal-majority regions and geographical continuity, not purely administrative lines — but the stronger geographical-zone example is the India-Pakistan boundary, which follows the Radcliffe Line drawn through rivers and watersheds. Wait — check carefully: India and Pakistan is an international boundary, not within a country. The question says "within a country" for (c) and (d). So (c) must be a domestic boundary. Jharkhand and Chhattisgarh were created from Bihar and Madhya Pradesh respectively, and their boundaries follow forested, hilly, and riverine geographical zones — that fits.

Fourth, demarcating boundaries within a country on administrative and political grounds. This refers to boundaries drawn for governance efficiency, often following district or historical administrative lines. Himachal Pradesh and Uttarakhand were separated from Uttar Pradesh on administrative and political grounds (to improve governance in the hill regions), not primarily on language or geography alone.

Thus the correct matching is:

• (a) Religious grounds → i. Pakistan and Bangladesh
• (b) Language grounds → iv. Himachal Pradesh and Uttarakhand
• (c) Geographical zones → iii. Jharkhand and Chhattisgarh
• (d) Administrative/political grounds → ii. India and Pakistan

But note: India and Pakistan is an international boundary, not "within a country". The question's phrasing "within a country" applies only to (c) and (d). So (d) must be a domestic boundary. Himachal Pradesh and Uttarakhand were created on administrative grounds, and (b) language grounds fits better with a different pair? Let us re-evaluate.

Actually, the standard NCERT-based classification is:

• (a) Religious → Pakistan and Bangladesh (partition of India on religious lines)
• (b) Language → India and Pakistan (the 1947 partition was not linguistic; this is a mismatch. The correct linguistic boundary is between India and Pakistan? No — that is religious. The correct linguistic boundary is between Himachal and Uttarakhand? No — that is administrative. The correct pair for language is actually India and Pakistan? That is wrong. Let me correct: The only clear linguistic boundary in the list is between India and Pakistan? No. The correct answer from standard sources is: (b) Language → iv. Himachal Pradesh and Uttarakhand (both are Hindi-speaking but separated on cultural-linguistic grounds? Actually, they were separated on administrative grounds. This is a known trick.)

Given the source material (NCERT Class 12 Political Science, Chapter 1), the correct matching is:

• (a) Religious → i. Pakistan and Bangladesh
• (b) Language → ii. India and Pakistan (the 1947 partition was based on religion, not language — so this is incorrect. The source says: "The partition of India in 1947 was based on religion." So (a) goes with ii. India and Pakistan. Then (b) language goes with i. Pakistan and Bangladesh? No — Bangladesh was created on linguistic grounds (Bengali language). So (b) → i. Pakistan and Bangladesh, and (a) → ii. India and Pakistan. That is the correct mapping.)

Thus:

• (a) Religious → ii. India and Pakistan
• (b) Language → i. Pakistan and Bangladesh
• (c) Geographical zones → iii. Jharkhand and Chhattisgarh
• (d) Administrative/political → iv. Himachal Pradesh and Uttarakhand

This is the standard answer.

Let’s first set the scene. Boundary delimitation — the process of drawing lines on a map — is never a neutral, purely technical exercise. It reflects the priorities and pressures of the time. Sometimes borders are drawn to separate communities along religious lines, as happened during the Partition of British India. At other times, language becomes the organising principle, especially within a multilingual country like India. Geographical features — rivers, mountain ranges, plateaus — often serve as natural, convenient dividers. And then there are purely administrative and political boundaries, created to improve governance, often by splitting larger states into smaller, more manageable units.

Now, look at the four principles listed:

• (a) Mapping of boundaries on religious grounds — This is about drawing borders to separate populations based on their faith. The most famous example in South Asia is the Partition of 1947, which created India and Pakistan. The Radcliffe Line was drawn hastily, using religious demography as the primary criterion. So (a) matches with ii. India and Pakistan.

• (b) Mapping of boundaries on grounds of different languages — India reorganised its states along linguistic lines in 1956, following the States Reorganisation Act. But the example here is i. Pakistan and Bangladesh. Bangladesh (formerly East Pakistan) was separated from West Pakistan by over a thousand miles of Indian territory, but the real divide was linguistic: the people of East Bengal spoke Bengali, while West Pakistan’s elite spoke Urdu. Language became the rallying point for Bengali nationalism, leading to the creation of Bangladesh in 1971. So (b) matches with i. Pakistan and Bangladesh.

• (c) Demarcating boundaries within a country by geographical zones — This refers to borders drawn using natural features like rivers, hills, or forests. iii. Jharkhand and Chhattisgarh share a border that largely follows the Chota Nagpur Plateau and the forested hills of the region. While these states were created primarily for tribal and administrative reasons, their boundary with each other is heavily influenced by geography — the plateau and the forest cover act as a natural divide. So (c) matches with iii. Jharkhand and Chhattisgarh.

• (d) Demarcating boundaries within a country on administrative and political grounds — This is about carving out new states for better governance, often without a strong linguistic or geographical basis. iv. Himachal Pradesh and Uttarakhand were both part of the larger state of Uttar Pradesh until 2000. Uttarakhand was created as a separate state to address the developmental needs of the hill region, distinct from the plains of Uttar Pradesh. The boundary between Himachal and Uttarakhand is largely an administrative decision, not driven by language or religion. So (d) matches with iv. Himachal Pradesh and Uttarakhand.
