Answer:
D. II and IV.
Step-by-step explanation:
A country has absolute advantage in the production of a good if it produces more quantity of the good when compared with other countries.
A country should specialise in the production of a good for which it has comparative advantage.
A country has comparative advantage in production if it produces at a lower opportunity cost when compared with other countries.
For country A,
One worker would produce = 200 / 200 = 1 bushel of corn
One worker would produce = 800 / 200 = 4 barrels of maple syrup.
For country B,
One worker would produce = 250 / 100 = 2.5 bushels of corn
One worker would produce = 500 / 100 = 5 barrels of maple syrup.
It can be seen that country B has absolute advantage in the production of both products because it produces more quantities of the good when compared to country A.
For country A
Opportunity cost of producing 1 bushel of corn = 4 / 1 = 4
Opportunity cost of producing 1 barrel of syrup = 1 / 4 = 0.25
For country B
Opportunity cost of producing 1 bushel of corn = 5 / 2.5 = 2
Opportunity cost of producing 1 barrel of syrup = 0.5
Country b has a lower opportunity cost when compared with country A in the production of corn. So, country B should specialise in the production of corn.
