Which is a valid counter-argument to the infant industry argument for protective tariffs?

Question

Quizplus · Accepted Answer

The counter-argument is that it is difficult to determine which infant industries will become mature industries with a comparative advantage, rendering the protective tariffs unnecessary or harmful in the long run. Options A, C, and D do not provide valid counter-arguments to the infant industry argument. Option A assumes that protective tariffs only benefit domestic firms, which is not necessarily true, and option C suggests an alternative policy without disproving the infant industry argument. Option D proposes a different protectionist policy, but it does not suggest why protective tariffs are ineffective or harmful.
