What does the Tenth Amendment state about powers not granted to the federal government?

The Tenth Amendment highlights the principle of federalism by stating that powers not delegated to the federal government by the Constitution, nor prohibited to the states, are reserved for the states or the people. This reflects the Founding Fathers' intent to limit the reach of the federal government and ensure that states retain significant authority over their own affairs. By doing so, it underscores the idea that the federal government is one of limited powers, with any powers not explicitly granted remaining under state jurisdiction or directly with the people, thereby protecting states' rights and individual liberties.

The other choices do not align with the Tenth Amendment's intent or text. For instance, the federal government does not automatically delegate remaining powers to the President, nor are these powers reserved for Congress, which is responsible for federal legislative authority. Lastly, the idea that such powers would simply be abolished contradicts the very essence of the Tenth Amendment, which is to preserve states' rights rather than eliminate them.
