If the President of India exercises his power as provided under Article 356 of the Constitution in respect of a particular State, then

Under Article 356(1)(b), when President’s Rule is imposed, the President declares that the powers of the State Legislature shall be exercisable by or under the authority of the Parliament. Option (a) is incorrect because the State Assembly is not automatically dissolved; it may be either suspended or dissolved at the discretion of the President. This question tests the core concept of Emergency Provisions and the specific constitutional shifts in federal authority during the breakdown of constitutional machinery in a State.
