Answer:
B. Tenth Amendment
Step-by-step explanation:
Article VI states that when state law is in conflict with federal law, federal law must prevail.
The Ninth Amendment states that all the rights not listed in the Constitution belong to the people, not the government.
And Article IV outlines the relationship between the states, as well as the relationship between each state and the United States federal government.
And, the correct answer, the Tenth Amendment states that the Federal Government only has those powers delegated in the Constitution, and therefore reserving state governments any powers not granted to the federal government.
