Answer:
The correct answer is A. Expressed powers are delegated powers of the state governments.
Step-by-step explanation:
The Expressed Powers of the Constitution are those powers conferred on the Federal Congress, which were delegated to them by the states. These belonged in principle to state governments, but they decided to delegate them to the central government for greater legal and administrative security and stability of the nation.
Expressed powers are enumerated on Article I Section 8 of the Constitution of the United States.
