Which of the following best describes expressed powers?

Expressed powers are those specifically mentioned in the United States Constitution. They are the direct powers granted to Congress and other branches of government that are explicitly outlined in the text of the Constitution. This means that the Constitution provides a clear framework for what these powers entail, such as the power to levy taxes, declare war, and regulate commerce.

In contrast to expressed powers, implied powers are not explicitly stated but are inferred from the powers that are expressly granted. The other options suggest either assumptions or powers not clearly defined, which do not accurately reflect the nature of expressed powers. Expressed powers are foundational to understanding the limits and capabilities of governmental authority as outlined by the Constitution.
