Correct option is D
The term "Closure" in parliamentary procedures refers to a rule under which further debate on a motion can be halted. It is a method employed to bring a debate to an end and proceed to voting, thereby preventing unnecessary prolonging of discussions. This tool is used to expedite the legislative process when a debate has been sufficiently discussed or when delaying tactics are being used.
Closure Motion: Under this rule, a member of the House can move a "closure" to cut short the debate. If the motion is accepted by the Speaker, the discussion is halted and the House proceeds to vote on the matter at hand.
