Q.Movement of goods and services among the countries :

The movement of goods and services among countries is International Trade, option (b).

International trade refers to the exchange of goods and services between two or more countries — it is trade that crosses national boundaries, comprising export trade, import trade and entrepot trade.

• Entrepot trade is only one part of international trade (importing goods to re-export them).
• Internal trade is trade within the boundaries of a single country. …

The answer is option (b) International Trade.

This is a narrower idea than international business, which includes not only trade in goods and services but also foreign investment, licensing, franchising, joint ventures and other cross-border commercial activities.

• Internal trade takes place within a country, so it is ruled out. …
