Answer:
B) It's the upper chamber of Congress and has one hundred members.
Step-by-step explanation:
The Senate and House of Representatives were created under the US Constitution during the Constitutional Convention. At this time, it was decided that every state would have two Senators, regardless of a states population. On the other hand, the House of Representatives would have representation based on a states population.
This is why the Senate currently has 100 Senators, as there are two from each of the fifty states.
