What defines the powers of the Executive branch in the Constitution?

The correct answer is that Article Two defines the powers of the Executive branch in the Constitution. This article outlines the roles and responsibilities of the President of the United States, including the authority to enforce laws, command the military, engage in foreign diplomacy, and appoint federal officials. It also establishes the process for Presidential elections and the criteria for impeachment.

In context, Article One actually relates to the Legislative branch, detailing the structures and powers of Congress, including the Senate and the House of Representatives. Article Three establishes the Judicial branch, which encompasses the court system and defines the powers of the judiciary. Article Four addresses the relationships among states and the federal government, including the Full Faith and Credit clause and regulations concerning state interactions. Therefore, Article Two is solely focused on the Executive branch, making it the definitive source for its powers.
