For how many years is a U.S. Senator elected?

A U.S. Senator is elected for a term of 6 years. This duration is established by the Constitution and is designed to provide senators with sufficient time to perform their legislative duties, engage in long-term planning, and establish relationships necessary for effective governance.

The 6-year term allows senators to be somewhat insulated from the immediate pressures of public opinion since they do not face re-election as frequently as members of the House of Representatives, who serve 2-year terms. This longer term is intended to encourage stability in the Senate, enabling senators to focus on broader issues that may require more time to address rather than just short-term goals aimed at winning elections.

In contrast, the other provided options do not align with the established term lengths set forth in the U.S. Constitution, which specifies that senators serve for 6 years. The frequency of elections in those incorrect choices would hinder the ability of senators to make long-term legislative commitments and potentially disrupt the continuity of governance.
