The correct option is D Parliament
The impeachment is to be initiated by either House of Parliament. The charges are to be framed in the form of resolution, signed at least by 1/4 th members of the total members of the House. The President has to be given a notice of 14 days in advance. The resolution is to be passed by 2/3 rd majority of the total members of the House and then it is to be sent to other House for investigation and decision. If the other House after investigation sustains the charges and passes the identical resolution with 2/3 rd majority of the total membership, the President ceases to hold office from the date such resolution is passed.
