Which is an executive power of the senate? a. appointing the president’s campaign staff b. confirming the president’s major appointments c. appointing the speaker of the house d. vetoing legislation that is approved by the house

B.

Speaker of the house is voted on by the House. The Senate has nothing to do with it. Campaign staff isn't controlled by anybody but the campaign manager (or theoretically the candidate), and definitely not the Senate. The Senate doesn't veto legislation, it votes on it. The Senate does, however, confirm the President's major appointments (Cabinet members and other secretaries).

Yes, they are always very triggered
