The correct option is C Swear in the members of the House and hold the charge till a regular Speaker is elected
Option C is the correct answer. A function of the Pro-Tem Speaker of the Lok Sabha is to swear in the members of the House and hold the charge till a regular Speaker is elected. Till a regular Speaker is elected, a pro tem Speaker administers oath to a new House and conducts proceedings. Under normal circumstances, a pro tem Speaker is sworn in by the President and an hour later, the Lok Sabha is convened and the newly-elected members are sworn in. The powers of the pro tem Speaker are not defined. But the pro tem Speaker does not surely have as much power as the permanent Speaker has.
