Answer:
B. The Senate
Explanation:
The Senate, as one of the two chambers of the United States Congress, consists of two elected senators of each state that serve a six-year term, and since the U.S. has 50 states, it has 100 senators.
In this body, the Vice President is the leader, as Article I, Section 3, Clause 4 of the U.S. Constitution states: The Vice President of the United States shall be President of the Senate, but shall have no vote, unless they be equally divided.
