Which article of the Constitution deals with the executive branch?

The article of the Constitution that deals with the executive branch is Article 2. This article outlines the powers, responsibilities, and the structure of the executive branch, which is headed by the President of the United States. It details the process of presidential elections, the qualifications required for the presidency, and the president's authority in enforcing laws, conducting foreign policy, and serving as the commander-in-chief of the armed forces.

The Constitution systematically divides government powers into three branches: the legislative, the executive, and the judicial. Article 1 describes the legislative branch, primarily the Congress, while Article 3 establishes the judicial branch, including the Supreme Court and other federal courts. Article 4 pertains to the states and the relationship between the states and the federal government. Thus, Article 2 is specifically dedicated to the operations and duties of the executive branch, making it the correct answer.
