The correct option is B Impeachment
The President can be removed from office before the completion of his term through the process of impeachment. The process can be initiated in either of the two houses. The charges are contained in a notice that has to be signed by at least one-quarter of the total members of that house. The notice is sent up to the President and 14 days later, it is taken up for consideration. A resolution to impeach the President has to be passed by a two-thirds majority of the total number of members of the originating house. It is then sent to the other house. The other house investigates the charges that have been made. If the second house also approves the charges made by special majority again, the President stands impeached.
