The correct answer is C) to clarify limits on the federal government.

The main purpose of the Tenth Amendment is to clarify limits on the federal government.

The 10th Amendment to the United States Constitution literally says "The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the States respectively, or to the people."

This amendment was included to clarify the limits on the federal government in that if the Constitution did not give a certain power to the federal government, then it gave it to the states or to the people of the US. This amendment was ratified on December 5, 1791.
