Which of the following is a power belonging to the states?

The power to provide schooling and education is indeed a responsibility allocated to the states within the framework of the U.S. Constitution. The Tenth Amendment explicitly reserves to the states all powers that are not delegated to the federal government, and education has traditionally been viewed as a state responsibility. This allows each state to establish its own educational systems, set curriculum standards, and manage public schools according to the needs of their populations.

In contrast, declaring war, making treaties, and creating an army are powers explicitly reserved for the federal government. The Constitution grants Congress the authority to declare war and fund national defense, reflecting the need for a unified national policy on these matters. As such, education represents a classic example of state power and autonomy in governance.
