To authorize the Indian Parliament to legislate on a subject in the State List in the national interest, which of the following is a constitutional requirement?

Explanation

Under Article 249 of the Indian Constitution, if the Rajya Sabha passes a resolution supported by not less than two-thirds of the members present and voting, declaring that it is necessary or expedient in the national interest that Parliament should make laws with respect to any matter in the State List, then it becomes lawful for Parliament to legislate on that subject. This does not require the President's prior permission or ratification by the state legislatures.
