The correct answer is (b), The Governor of a State.
The Constitution of India does not contain any provision for the impeachment of the Governor of a State. The Governor is appointed by the President of India on the advice of the Central Council of Ministers. The Governor can be removed from office by the President on the ground of proved misbehaviour or incapacity.
The President, the Vice President, and the Chief Justice of India can be impeached by the Parliament. The impeachment process is initiated by a motion for impeachment, which must be signed by at least one-fourth of the total number of members of the House of the People. The motion is then referred to a committee of the House, which investigates the charges and submits a report to the House. If the report of the committee recommends impeachment, the House then votes on the motion. If the motion is passed by a two-thirds majority of the members present and voting, the President, the Vice President, or the Chief Justice of India is removed from office.
The impeachment process is a very serious matter and is only used in cases of grave misconduct. The process is designed to ensure that the highest offices in the country are held by people of integrity and probity.
