Which Article of the U.S. Constitution establishes the legislative branch and outlines its powers?

• A. Article II
• B. Article I
• C. Article III
• D. Article IV

Answer: (B)

The main idea is where the legislative branch is created and what powers it has. Article I does that. It establishes Congress, a two‑house lawmaking body, and lists the powers Congress can exercise—such as collecting taxes, regulating commerce, coining money, declaring war, and raising armies. It also includes the Necessary and Proper Clause, which lets Congress pass laws needed to carry out these powers. This focus on creating the legislative branch and outlining what it can do is what sets Article I apart from the other articles, which organize the executive and judiciary and address relations among states. So, Article I is the part of the Constitution that establishes the legislative branch and outlines its powers.
