Which of the following is a concurrent power?

• A. The Power to Coin Money
• B. The Power to Regulate Trade Between States
• C. The Power to Collect Taxes
• D. The Power to Establish National Defense

Answer: (C)

Concurrent powers are those that both the national government and the state governments can use at the same time. The power to collect taxes fits this idea because both levels of government need revenue to operate and fund public services, so both can levy taxes within their own areas of authority (federal taxes like income taxes and states’ taxes like sales or property taxes).

The other options are not concurrent. Coining money is an activity reserved for the national government, not the states. Regulating trade between states is a federal power, since it deals with interstate commerce, while states regulate commerce within their borders. Establishing national defense is clearly a federal responsibility.
