The correct answer is D) One-tenth of the total membership.
Article 100(3) of the Constitution of India stipulates that the quorum to constitute a meeting of either House of Parliament shall be one-tenth of the total number of members of the House. This means that for a valid sitting of the Rajya Sabha (or Lok Sabha), at least 1/10th of its total members must be present.
The total strength of the Rajya Sabha is currently 245 members. Therefore, the quorum required for a Rajya Sabha sitting is 1/10th of 245, which is 25 members. If there is no quorum, the presiding officer (Chairman or Deputy Chairman) may adjourn the House or suspend the meeting until there is a quorum.
