The correct answer is option 3, Manipur. Manipur has had the President`s Rule imposed on it more times than any other state listed in the options. President`s Rule is a provision in the Indian Constitution that allows the President to take over the administration of a state in certain exceptional circumstances, such as when there is a breakdown of constitutional machinery in the state. However, it is important to note that President`s Rule is not imposed directly by the President, but is usually recommended by the state`s Governor.

In the case of Manipur, the state has seen political instability and disruptions over the years, with frequent changes in government leadership and instances of violence and civil unrest. This has led to the imposition of President`s Rule multiple times in order to restore law and order and ensure the smooth functioning of the state administration.

It is worth mentioning that the imposition of President`s Rule is a serious measure and is intended to be temporary. The state`s normal functioning is restored once the situation improves and a democratically elected government is installed.
