Which of the following is a power of the federal government?

The power to declare war is explicitly granted to the federal government by the Constitution, specifically in Article I, Section 8. This section outlines the powers of Congress, including the authority to make war, raise and support armies, and provide for the common defense. This power is reserved for the federal government and highlights its central role in national security and foreign relations, differentiating it from state powers, which typically involve more localized matters.

In contrast, issuing driver's licenses, managing local schools, and establishing zoning laws are all powers that are primarily reserved for state governments. These responsibilities pertain to state jurisdiction and concern the administration of services and regulations that affect daily life within the states. The distinction between federal and state powers is a key component of the federalist system established by the Constitution.
