Answer:
Option (D) is correct.
Explanation:
In United states:
Can produce 25 tons of steel or 250 automobiles,
Opportunity cost of producing a ton of steel = 250 ÷ 25
= 10 automobiles
Opportunity cost of producing 1 automobile = 25 ÷ 250
= 0.1 tons of steel
In Japan:
Can produce 30 tons of steel or 275 automobiles,
Opportunity cost of producing a ton of steel = 275 ÷ 30
= 9.17 automobiles
Opportunity cost of producing 1 automobile = 30 ÷ 275
= 0.11
Therefore,
United States has a comparative advantage in producing automobiles because the opportunity cost of producing automobiles is lower than the Japan.
Japan has a comparative advantage in producing steel because the opportunity cost of producing steel is lower than the United states.
