Correct Option (d)
Article 249 of the Indian Constitution empowers the Parliament to legislate on subjects enumerated in the State List if the Rajya Sabha declares, by a resolution, that it is necessary or expedient in the national interest to do so. This resolution must be supported by a majority of not less than two-thirds of the members of the Rajya Sabha present and voting. Such a resolution remains in force for a period not exceeding one year, but can be extended for another year by a fresh resolution.
Incorrect Options
Options (a) and (b) are incorrect because Article 249 specifically vests this power in the Rajya Sabha, not the Lok Sabha. The Lok Sabha plays no role in initiating such a resolution under this article.
Option (c) is incorrect because while the Rajya Sabha is the correct house, the required majority for passing such a resolution is not a simple majority. As per Article 249, it mandates a special majority of not less than two-thirds of the members present and voting.
