The table below shows the tons of steel and concrete that can be produced by the United States and France in an hour

Answer: A

Absolute advantage is the higher production in comparison.

As per the data given, the country-F has absolute advantage in both steel and concrete, because the steel production of F is 100 units and it is higher than 25 units of the US, and the concrete production of F is 200 units and it is higher than 100 units of the US.

Comparative advantage is the lower opportunity cost of production.

In case of steel production the country-F has lower OC than the US, since 2 < 4

In case of concrete production the US has lower OC than the US, since 0.25 < 0.50

Therefore, country-F has comparative advantage in steel and the US has comparative advantage in concrete.

Therefore, option-A is correct.

Other options are not correct:

Option B: the US doesn’t have any absolute advantage.

Option C: country-F has comparative advantage in steel only, but not in concrete.

Option D: the comparative advantage in concrete goes to the US, but not to the country-F.
