The correct answer is Speaker will cast vote in the first instance in the House. Key Points - The Speaker is the member of the lower house, elected by a simple majority. - Speaker can resign by tendering his resignation to the Deputy Speaker. - Speaker can be removed by a simple majority (i.c. more than 50% votes). - He can exercise his vote only when the House is divided equally on any question, called casting vote. Hence it is the correct answer. - At present, the Speaker of Lok Sabha is Om Birla.
