Which of the following is an example of a concurrent power shared by the national and state governments?

This power is exclusively held by the national government, as outlined in the U.S. Constitution. Only Congress has the authority to declare war, reflecting the need for a unified national defense strategy and preventing states from engaging in independent military actions.

The power to coin money is also reserved solely for the national government. The Constitution grants this authority to Congress, ensuring a stable and uniform currency throughout the country, which is a critical function of a centralized economic system.

While both national and state governments can establish courts, the specific types of courts and their jurisdictions can vary significantly. However, this power does not exemplify a concurrent power since it is more about the structure of the judicial system rather than a shared function.

Regulating interstate commerce is primarily a power of the national government. The Constitution grants Congress the authority to regulate trade between states to maintain a cohesive national economy, which is distinct from concurrent powers.
