Answer:
A) II only
Step-by-step explanation:
A company or country producing goods and services at a lower opportunity costs gain comparative advantage over other firms or nations. It means the country can offer the product to the market at a lower price than any others. A lower opportunity cost implies the benefits forfeited in the production costs less.
A low cost of production or cheaper inputs makes the opportunity cost of production low. A country that can manufacture certain goods and services at a lower price should produce in bulk for the export market. Similarly, the country should import what other countries can produce at a lower price. Trading from this perspective facilitates prudent use of the factors of production.
