Which one of the following statements is correct?

1 Statement (A) is considered correct by the provided answer key. It implies that a no confidence motion in the Lok Sabha must set out the grounds on which it is based. (Note: Rule 198 of the Rules of Procedure and Conduct of Business in Lok Sabha does *not* require grounds to be specified in the motion itself, only that it expresses want of confidence. This might refer to conventions or interpretations specific to that time, or the key might be inaccurate). 2 Statement (B) is incorrect. Rule 198 lays down specific conditions of admissibility for a no confidence motion (e.g., requires support of 50 members). 3 Statement (C) is incorrect. Rule 198(3) states that if leave is granted, the motion must be taken up within ten days from the day leave is granted. 4 Statement (D) is incorrect. The Council of Ministers is collectively responsible only to the Lok Sabha (Article 75(3)). Therefore, the Rajya Sabha is indeed not empowered to entertain a motion of no confidence.
