<em>B. Nullification Crisis.</em>
Explanation:
The Tenth Amendment in the United States Constitution grants all of the powers that are not specifically granted to the government, to the states and to the people. This was very important, as many people were scared that the government would abuse their power onto them or have too much power in general. This was a way for the states and people to still have power, while still having a strong government.
The Nullification Crisis was a huge debate and issue on protective tariffs. The Southern states opposed tariffs, as the majority of their income was shipping goods to foreign countries. If protective tariffs were to be put on, it would be more expensive and they would ultimately lose money. The Southerners deemed this to be unconstitutional, they thought the federal government did not have the right to put these tariffs on them.
The debate about states' rights came along and tensions between the Southern states and the federal government would arise.
