A Supreme Court or High Court judge can be removed by the Parliament by:

special majority

The correct answer is Option 3 - special majority

A Supreme Court or High Court judge can be removed by Parliament only through a process of impeachment, which requires a special majority. Specifically, a judge can be removed by a resolution passed by both Houses of Parliament with a majority of the total membership of that House and by a majority of not less than two-thirds of the members present and voting.
