The correct option is B Dismiss the Council of Ministers by moving an adjournment motion
An adjournment motion is to draw attention of the House to matters of grave public importance. The adjournment motion requires the support of at least 50 members. Only the Lok Sabha is allowed to pass this motion and not Rajya Sabha, it is because the adjournment motion involves criticism against the government. Thus, Lok Sabha can't dismiss the Council of Ministers by moving an adjournment motion as one of the restriction on such motion is that the adjournment motion should not involve any question that can be raised on a separate motion. Thus, censure motion can be moved against an individual minister or a group of ministers or the entire council of ministers.
