A Basic Flaw in the Infant-Industry Argument Is That

A basic flaw in the infant-industry argument is that

A) most industries need protection when they are mature,not when they are first established.
B) the amount of the tariff is unlikely to have much impact on the success of an infant industry.
C) once a tariff is granted,political pressure will likely prevent the withdrawal of the tariff even when the industry matures.
D) domestic consumers will continue to buy the foreign products anyway,regardless of the tariff.
