A. concurrent powers
B. enumerated powers
C. prohibited powers
D. reserved powers

Which makes sense for "at the same time" ?

Is it concurrent powers?

Yes, concurrent.

The powers that are exercised by both the national government and state governments at the same time are called concurrent powers. To understand this, let's break down the options:

A. Concurrent powers: These are powers that are shared by both the national government and state governments. Examples of concurrent powers include the ability to collect taxes, establish courts, and maintain law enforcement.

B. Enumerated powers: These are powers specifically listed in the U.S. Constitution for the national government. Enumerated powers include the power to declare war, regulate commerce, and coin money.

C. Prohibited powers: These are powers that are specifically denied to the national government or state governments by the U.S. Constitution. Examples of prohibited powers include the power to grant titles of nobility, pass ex post facto laws, and suspend habeas corpus.

D. Reserved powers: These are powers that are not specifically granted to the national government by the U.S. Constitution and are therefore reserved for the states. Reserved powers include the power to regulate intrastate commerce, establish public schools, and control elections.

Given the options, the correct answer is A. concurrent powers, as they represent the powers that are exercised by both the national government and state governments at the same time.
