The correct answer is D. The US Constitution established six-year terms for members of the Senate in order to allow senators to focus on long term national issues.

The fathers of the Constitution created a bicameral Congress for the desire to have two chambers to be supervised among them. The intention of the House of Representatives was to be the "people's chamber", which would be extremely sensitive to public opinion. The other chamber was intended to represent the states. Until 1913, senators were elected by state legislatures and not by popular vote; in that year the Seventeenth Amendment was promulgated, which established the senatorial election via direct popular election. This would be a forum of greater deliberation, where the six-year periods would allow the Senators not to depend totally on public opinion as in the cases of short periods, instead focusing of larger issues.
