The United States Senate is composed of 100 total members, with each of the 50 states being represented by two senators. Option A is incorrect because there are more than 50 states in the United States and each state is represented by more than one senator. Option C is incorrect because 435 is the total number of members in the United States House of Representatives, not the Senate. Option D is incorrect because 538 is the total number of members in the United States Congress, which includes both the House of Representatives and the Senate. Therefore, option B, 100, is the correct answer.
