Answer:
B. Alpha should specialize in Y and Beta in X
Explanation:
This is in line with the theory of absolute advantage postulated by Adam Smith where he was of the opinion that country should specialize in those commodities it can produce at the lower absolute cost than other countries. He added that trade is mutually beneficial if one nation has an absolute advantage in the production of one good and the other nation has absolute advantage in the production of the second good. Since alpha can produce more Y and beta can produce more X, they should each focus on producing those products they can produce more efficiently.
