Where are the powers of the U.S. Constitution specifically enumerated?

The powers of the U.S. Constitution are specifically enumerated in Article I, Section 8. This section outlines the enumerated powers of Congress, detailing the specific authority that Congress holds, such as the power to levy taxes, regulate commerce, declare war, and maintain armed forces, among others. This enumeration serves as a critical component of the Constitution, establishing the framework for federal legislative authority and ensuring a clear understanding of the limits and responsibilities of Congress.

The other choices do not provide this specific enumeration of powers. The Bill of Rights contains amendments that protect individual liberties and rights but does not detail governmental powers. Article I, Section 1 establishes the legislative branch but does not list specific powers. The Preamble serves as an introductory statement that outlines the purposes of the Constitution but does not enumerate powers. Thus, Article I, Section 8 is the correct answer as it directly lists the specific powers granted to Congress.
