c. the tariff protected industries in the North from foreign competition
Explanation:
The tariff of 1816 was implemented in order to serve as a measure of protection for the industries in the North. While this was good for the industries in the North, it was a measure that was sectional, and it neglected the interest of the South. The South actually suffered and was recording losses because of the tariff, as it made its agricultural goods less competitive on the market by having higher prices. This led to lot of tensions and disagreements about the tariff between the North and the South.
