Answer:
B) 1 corn for 1 auto
Step-by-step explanation:
A country possesses a comparative advantage in the production of a product if the opportunity cost, in terms of the amount of other products that it gives up to produce this product, is lower than it is for its trading partners.
If one nation is able to produce a good at a lower opportunity cost than another, it has a comparative advantage in that good.
For Mexico and United States, 1 corn for 1 auto would not be potential terms of trade.
