Answer:
A
Explanation:
Enumerated powers are those specifically given to the federal government. Concurrent powers are powers given to both the state and federal government, and the states do not have the power to coin money or raise an army. Moreover, we know that C is incorrect as there is a United States currency and military (thus someone has to make them). Finally, reserved powers are those only given to the states via the 10th Amendment. Therefore, A is your answer.
