Nations engage in international trade because of difference in?

A.

Absolute cost

B.

Comparative cost

C.

Fixed cost

D.

Variable cost

Correct answer is B

The principle of comparative cost states that; 
international trade takes place between two countries when the ratios of comparative cost of producing goods differ, and each country would specialise in producing that commodity in which it has a comparative advantage.

Comparative cost advantage is when a country produces a good or service for a lower opportunity cost than other countries.
