Answer:
A)Infant-industry argument
Explanation:
We are informed about a Supposed policy debate over whether the United States should impose trade restrictions on imported ball bearings. Whereby
Domestic producers of ball bearings send a lobbyist to the U.S. government to request that the government impose trade restrictions on imports of ball bearings.
In the case whereby, The lobbyist claims that the U.S. ball-bearing industry is new and cannot currently compete with foreign firms, the justifications the lobbyist was using to argue for the trade restriction on ball bearings is Infant-industry argument.
Infant-industry argument can be regarded as an economic rationale that provides protection for new industries that are yet to reach a certain economic scale like the existing industries, this theory offer protection to this new/developing industry from some form pressure as well as their products that can emerge from compitition from other mature industries.
