Which of the following is a check on the power of the executive branch?

A) the ability of Congress to impeach the president
B) the restriction of the ability to declare war to Congress
C) the judicial branch's ability to limit or overturn executive branch decisions
D) All of these answers are correct.

Each of these is a check on the power of the executive branch built into the government of the United States. Congress reserves many rights, such as the right to declare war or even remove the president from office for high crimes and misdemeanors. The judiciary also has the power to limit or overturn executive decisions. However, the executive has many powers that serve as checks on both of the other branches, such as the power to veto laws passed by Congress or to appoint (with the approval of Congress) members of the judiciary.
