Step 1: Understanding the Concept:
The question requires identifying the correct statement about the nature of international trade based on a country's stage of economic development, as explained in the passage. The passage states, "At different stages of economic development of countries, the nature of items traded undergo changes."
Step 3: Detailed Explanation:
\[\begin{array}{rl} \bullet & \text{(A) This is a classic pattern of trade. Countries specializing in agriculture (often developing countries) export agricultural products and import manufactured goods from industrialized nations. This statement is true.} \\ \bullet & \text{(B) This statement reverses the roles. Industrialized nations typically export machinery and finished products and import raw materials and certain food grains.} \\ \bullet & \text{(C) This is illogical. Countries that are pioneers in a technology would export it, not import it, especially not from less technologically advanced nations.} \\ \bullet & \text{(D) This directly contradicts the passage which says, "At different stages of economic development of countries, the nature of items traded undergo changes."} \\ \end{array}\]
Step 4: Final Answer:
The only true statement is that agriculturally important countries typically trade their agricultural products for manufactured goods.
