Which of the following is a power of the states?

• A. Declare war
• B. Make treaties
• C. Print money
• D. To give a driver's license

Answer: (D)

State governments hold many regulatory powers over daily life, exercised through their police powers. Issuing a driver's license is a typical example of this state-level authority, because it regulates who may drive within a state and helps ensure road safety. The Constitution reserves many powers not delegated to the federal government for the states, a balance clarified by the Tenth Amendment.

In contrast, some powers are explicitly federal: declaring war, making treaties with other nations, and printing money are classic national authorities that coordinate actions across states and with the world, and they are not handled by the states. Therefore, issuing a driver's license is the state’s power, while the other options are federal powers.
