Which amendment addresses the rights of states and the people?

The 10th Amendment is the correct answer because it specifically addresses the distribution of power between the federal government and the states. It states that any powers not delegated to the federal government by the Constitution, nor prohibited to the states, are reserved to the states or to the people. This amendment reinforces the principle of federalism, emphasizing that states have their own rights and powers that are independent of the federal government.

The significance of the 10th Amendment lies in its affirmation of state sovereignty and the rights of individuals. It serves as a reminder that the federal government has limited authority and that states retain certain powers that are essential for local governance.

In contrast, the other amendments mentioned in the choices focus on different issues: the 9th Amendment discusses the enumeration of rights not specifically listed in the Constitution; the 11th Amendment deals with judicial jurisdiction and the ability of states to be sued; while the 12th Amendment outlines the procedure for electing the President and Vice President. Hence, the 10th Amendment uniquely encapsulates the rights of states and the people.
