The President can be removed by the way of impeachment which can be made only

The correct answer is option 3 i.e. Either House of the Parliament.

The President in India can be removed only in case of a violation of the constitution.
The meaning of the phrase ‘violation of the constitution has not been mentioned in the Indian Constitution.
Article 61 of the constitution provides for the Impeachment of the President of India.
The charges of impeachment can be initiated in either house of the Parliament.
The charges need to be signed by 1/4th of the members of the House and a 14-day notice should be given to the President.
After the impeachment resolution is passed by a majority of the two-thirds of the majority of that House, it is sent to the other to investigate the charges.
If the other house also passes the resolution for impeachment by a majority of two-thirds of the total membership of that House, the President then stands impeached from his office from the date on which the resolution has been passed.
