The correct options are
C No explicit reason needs to be specified to admit a No-Confidence Motion.
D If it is approved, then the entire Political Executive must resign
A No-Confidence Motion is raised against the ruling party. Ministers need not state a prior reason for raising it. Even when grounds are mentioned in the notice and read out in the House, they do not form part of the motion. The motion needs 50 members to nod to be admitted, and half of the total members in Lok Sabha to pass, and if it gets approved, then the Prime Minister and the Council of Ministers must immediately resign.
