Which of the following is not a branch of government?

The correct answer is the Administrative branch, as it is not recognized as one of the three main branches of government established in the United States Constitution. The U.S. government is divided into three branches: the Executive, which is responsible for enforcing laws and is headed by the President; the Legislative, which makes laws and is comprised of Congress (the House of Representatives and the Senate); and the Judicial, which interprets laws and is made up of the court system, including the Supreme Court.

The Administrative functions often fall under the Executive branch; however, they do not constitute a separate branch of government. Administrative agencies exist to implement and enforce specific laws and regulations, but they operate within the framework of the Executive branch rather than being independently organized as a distinct branch. This distinction is key in understanding the division and balance of power within the U.S. government.
