How many U.S. senators are there?

The correct response is based on the structure of the United States Senate, which is composed of two senators from each of the 50 states. This design, established in the U.S. Constitution, ensures equal representation of each state in the Senate regardless of population size. Consequently, with 50 states contributing two senators each, the total number of U.S. senators sums to 100. This framework plays a critical role in the legislative process and maintaining a balance of power among the states within the federal government. The other choices reflect misconceptions about the number of legislators in different bodies of government or are simple arithmetic misjudgments, but none of those accurately describe the Senate's composition.
