Answer:
C. Leadership of a political party
Step-by-step explanation:
Article II, which is the Article that outlines the Executive branch general structure and function, gives the President the authority to appoint, with the advice and consent of the Senate, “ambassadors, other public ministers and consuls, judges of the Supreme Court”, and others US officers and it also designates him or her as “commander in chief of the Army and Navy of the United States, and of the militia of the several states, when called into the actual service of the United States.”
The presidential power of veto is also found in the US Constitution, more specifically in Section 7 of Article I, when it states that when Congress passes a bill, it has to be presented to the President, who has the choice to approve the bill, veto the bill or sit on the bill.
As for option C, this statement is false: the document says nothing about giving the President leadership of a political party.
