Answer :
It is describing the job of the president. The president is the executive branch ( judges= judicial branch and representatives and senators belong to the legislative branch). The president's job is to mainly enforce and carry out laws. He also appoints judges and other political figures. He is sometimes referred to as the commander in chief.
Use the following quote to answer the question.
"The supreme executive power shall be vested in a governor, who shall be commander-in-chief of all military forces of the state not in active service of the United States. The governor shall take care that the laws be faithfully executed, commission all officers of the state and counties, and transact all necessary business with the officers of government."
The position described in the quote above compares closest to the national position of
- U.S. representative
- U.S. president
- U.S. senator
- U.S. federal judge
U.S. President is the answer if your specifically meaning in this form.
