The correct answer is C. There are no limits on debate in the United States Senate. The Senate has a tradition of unlimited debate which has developed due to its relatively small size. The "filibuster" is one such example of this. The House of Representatives DO have limits, as well as two year terms and a Speaker who leads the members.
