Answer 1

Answer:

A

Explanation:

A country gains from trade if it specialises in the production of the good for which it has a comparative advantage

A country has comparative advantage in production if it produces at a lower opportunity cost when compared to other countries. this means that the country can produce the good by forgoing fewer alternative products

For example, country A produces 10kg of beans and 5kg of rice. Country B produces 5kg of beans and 10kg of rice.  

for country A,  

opportunity cost of producing beans = 5/10 = 0.5

opportunity cost of producing rice = 10/5 = 2

for country B,  

opportunity cost of producing rice = 5/10 = 0.5

opportunity cost of producing beans = 10/5 = 2

Country A has a comparative advantage in the production of beans and country B has a comparative advantage in the production of rice
