The correct answer is A. a tariff. A tariff is a tax or duty imposed on goods that are imported or exported between countries. In this case, Country A charges a 35% tax on automobiles imported into the country. To determine the answer, it is important to understand the definitions of each option:

In the given scenario, there is no mention of a limit or ban on the quantity of imported automobiles, nor is it related to specialization. Therefore, the correct answer is A. a tariff.
