Suppose there is a policy debate over imposing trade restrictions on imported steel rods in the United States. A senator from a state with several steel-rod factories argues that the government should impose a tariff on steel rods, because they are a necessary input into the production of various weapons. Free trade would make the USA overly dependent on foreign countries for the supply of steel; rods. In case of a war, the USA might not be able to make or purchase enough of them and , therefore, would not be able to make enough weapons to defend itself.

The senator is using the _______________ argument to justify the trade restriction on steel rods.

A- Saving-domestic-jobs

B- Infant-industry

C- Antidumping

D- National-defense-auto-spell
