The response that best explains the limits to the power of the executive branch established in the U.S. Constitution is:
The president is elected for a four-year term, and one person can have only two terms as president.
This response accurately reflects the limitations placed on the presidency, specifically the term limits established by the 22nd Amendment, which prevents any individual from serving more than two terms as president. The other options misrepresent the constitutional process and the balance of powers among the branches of government.
