How many U.S. Senators are there?

The correct answer is one hundred (100) because the United States Senate is composed of two Senators from each of the fifty states, regardless of the state's population. This structure contributes to a balanced representation in Congress, allowing smaller states equal representation alongside larger states. Therefore, with fifty states each contributing two Senators, the total number of U.S. Senators is one hundred. The other options misrepresent the structure of the Senate either by suggesting fewer or more representatives or by representing a number not aligned with the established framework of U.S. governance.
