Answer:
b. The U.S. has an absolute advantage in computer chips manufacturing.
Step-by-step explanation:
South Korea's opportunity cost of producing 1 bed linen = 100/50 = 2 computer chips. Where, US' opportunity cost of producing 1 bed linen = 150/100 = 1.5 computer chips.
As US' opportunity cost of producing 1 bed linen is less than that of South Korea's , Therefore, US has comparative advantage in production of bed linen and south korea will have comparative advantage in production of the other good i.e. computer chips.
Now looking at the absolute advantage, US has absolute advantage in production of both goods i.e. Bed linen and computer chips, because using same one hour of labor input, US can produce more bed linen and computer chips than South korea does.
