Answer:
C. 1200
Explanation:
Based on the Appointments Clause of the United States Constitution and law of the United States, there exist certain number of federal positions appointed by the president of the United States that needs confirmation (advice and consent) of the United States Senate.
These "PAS" (Presidential Appointments requires Senate confirmation) positions, as well as other types of federal government positions, are made available in the United States Government Policy and Supporting Positions otherwise known as Plum Book, which is released after each United States presidential election.
Hence, in a recent Congressional Research Service study, it was estimated that approximately 1200-1400 positions require Senate confirmation.
