Correct Option
Statement 1 is correct. Article 249 of the Constitution grants the Rajya Sabha the exclusive power to declare that it is necessary or expedient in the national interest for Parliament to legislate with respect to a matter enumerated in the State List. Such a resolution must be supported by not less than two-thirds of the members present and voting. This provision underscores the Rajya Sabha's role in representing the interests of the states at the Union level.
Incorrect Options
Statement 2 is incorrect. Proclamations of Emergency, including National Emergency (Article 352), President's Rule (Article 356), and Financial Emergency (Article 360), require approval by resolutions passed by both Houses of Parliament, i.e., the Lok Sabha and the Rajya Sabha. The approval is not solely within the purview of the Lok Sabha.
Option (b) is incorrect as Statement 2 is false.
Option (c) is incorrect because only Statement 1 is correct.
Option (d) is incorrect as Statement 1 is correct.
