President's control order in the executive branch through their power to

A. Replace supreme court justices
B. Nominate their own cabinet
C. Select majority speakers and whips
D. Remove state governors

The correct answer is B. Nominate their own cabinet.

The President's control over the executive branch is mainly exerted through their power to select and nominate their own cabinet members. The President appoints individuals to specific positions within the executive branch, such as secretaries of various departments, ambassadors, and agency heads. These individuals, once confirmed by the Senate, work closely with the President to implement their policy agenda and manage the day-to-day operations of the executive branch.
