The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The constitutional power that Congress has over the bureaucracy is that the United States Congress can exert control over the bureaucracy by overseeing and supervising the public funds that allow its operation. So Congress can control the funds the government offices need to operate and the members of Congress can approve the appointments of the President to the cabinet and other public offices. Congress forms committees to evaluate the necessities of the US bureaucracy and many times hold hearings with the heads of government departments to make sure the funds are justified.
