The Senate is referred to as the upper house of Congress primarily because it represents states equally. Each state, regardless of its population size, is allotted two Senators. This equal representation ensures that all states have an equal voice in the legislative process. In contrast, the House of Representatives is based on population, meaning states with larger populations have more representatives, which can lead to a dominance of larger states in that chamber.

While the other options may reflect certain attributes of the Senate, they do not contribute as fundamentally to its identity as the upper house. The fact that Senators serve longer terms than House members provides stability but does not define the nature of the chamber's role in the legislative process. The exclusive rights to tax belong to Congress as a whole, not specifically to the Senate, and the total number of members in the Senate is fewer compared to the House, which is the opposite of what might be suggested by the idea of an "upper house." Thus, the correct characterization of the Senate's status comes from its equal representation of states.
