The powers that are exercised by both the national government and state governments at the same time are known as concurrent powers.
Here’s a brief overview of the other options:
- Enumerated powers: These are powers specifically listed in the Constitution for the national government.
- Prohibited powers: These are powers that are specifically denied to either the national government, the state governments, or both.
- Reserved powers: These are powers that are not granted to the national government and are reserved for the states.
So, the correct answer is concurrent powers.
