The correct answer is option b.
Step-by-step explanation:
According to the Heckscher-Ohlin theory, a capital abundant country specializes in capital intensive goods. Thus it produces capital intensive goods and exports them, and imports labor-intensive good.

This was proved by W. Leontief through empirical evidence. Thus, it is called the Leontief paradox.
