Q.Match the terms given under Column 'A' with their functions given under Column 'B' and select the answer from the options given below:
Column I – Column II
A. Lymphatic System – i. Carries oxygenated blood
B. Pulmonary vein – ii. Immune Response
C. Thrombocytes – iii. To drain back the tissue fluid to the circulatory system
D. Lymphocytes – iv. Coagulation of blood

Matching each term to its function: the lymphatic system's role is to drain back the tissue fluid to the circulatory system (iii); the pulmonary vein carries oxygenated blood, from the lungs back to the heart (i); thrombocytes bring about the coagulation of blood (iv); and lymphocytes carry out the immune response (ii). This …

Each of these four terms has a distinct, well-defined role in body fluids and circulation:

• The lymphatic system is the widespread network of vessels that gathers up tissue fluid escaping from the blood capillaries and returns it to the major veins, putting it back into general circulation — matching (iii), to drain back the tissue fluid to the circulatory system.
• The pulmonary vein is the vessel that carries the oxygenated blood produced in the lungs back to the left atrium of the heart — matching (i), carries oxygenated blood. …

Method: Solving a Matching-Type MCQ With Pre-Built Answer Options

Use this approach whenever a matching question gives you Column I, Column II, and then several lettered options that each propose a full set of pairs.

Steps

Step 1: Solve each Column I item independently first, as if there were no options given

Write down (mentally or on paper) what YOU think each term matches to, using its defining fact, before glancing at options (a)-(d).

Step 2: Compare your own matches against each lettered option

Look for the ONE option that agrees with ALL of your matches — not just one or two of them.

Step 3: If two options look close, isolate the single pair where they differ …
