Question

the 10th amendment to the u.s. constitution: reserves powers not delegated to the federal government for the states abolishes state governments establishes the separation of powers within the federal government grants the federal government supremacy over the states

Explanation:

The 10th Amendment to the U.S. Constitution states that powers not delegated to the federal government by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people. The option "Abolishes state governments" is incorrect as state governments exist. "Establishes the separation of powers within the federal government" is related to the structure of federal branches (not the 10th Amendment). "Grants the federal government supremacy over the states" is more related to the Supremacy Clause, not the 10th Amendment. So the correct option is the one about reserving powers for the states.

Answer:

A. Reserves powers not delegated to the federal government for the states
