The correct answer is option 4: There is a Constitutional breakdown. When there is a situation where the constitutional machinery in a state fails to function properly, the President`s Rule can be imposed. This can happen due to various reasons such as when there is a breakdown of law and order, failure of the state government to carry out its constitutional duties, or if there is a political crisis and no party or coalition can form a stable government. In such cases, the President, upon receiving a report from the Governor of the state or otherwise, can declare a state of emergency and assume direct control over the administration of the state. This ensures the smooth functioning of the state and the protection of the interests of the people.
