Which of the following are powers that are exercised by both the national government and state governments at the same time?

a) concurrent powers

b) enumerated powers

c) prohibited powers

d) reserved powers

Answer: Concurrent powers.

Explanation: concurrent power is a political power independently exercisable by both federal and state governments in the same field of legislation. The United States constitution delegated Power to the federal government that is also held by the states. Concurrent power is a power shared by both the federal and state government. In the United State for instance, examples of the concurrent power shared by both the national and state government include the power to tax, create lower court and construction of roads. Concurrent powers are exercised simultaneously within the same territory, the same body of citizens and regarding the same subject matter.
