Which Article of the U.S. Constitution provides legislative powers to Congress?

The correct answer is C, as Article 1 of the U.S. Constitution explicitly establishes the legislative branch of the federal government, which is Congress. Article 1 outlines the structure, powers, and responsibilities of Congress, including the authority to make laws, impose taxes, regulate commerce, and declare war, among other legislative functions. This foundational article sets the groundwork for how the legislative branch operates and its role within the federal government, making it crucial for understanding the separation of powers in the U.S. system.

In contrast, Article 2 pertains to the executive branch and outlines the powers and duties of the President, while Article 3 establishes the judicial branch and the authority of the federal courts. Article 4 focuses on the relationships between states and the federal government, including the process for admitting new states and ensuring a republican form of government in each state. Each of these articles has its own distinct purpose and does not grant legislative powers to Congress.
