Correct option is A
Statement 1 is correct.
When a resolution for the removal of the Speaker of the Lok Sabha is under consideration, the Speaker is not allowed to preside over the sitting of the Lok Sabha during that period. However, the Speaker is permitted to be present in the House while the resolution is being discussed. This is to ensure impartiality during the proceedings.
Statement 2 is incorrect.
When a resolution for the removal of the Speaker is under consideration, the Speaker can indeed participate in the proceedings. The Speaker is allowed to speak and take part in the discussions regarding the resolution, despite not being able to preside over the session. This allows the Speaker to present their case or respond to the allegations made in the resolution.
Statement 3 is incorrect.
When a resolution for the removal of the Speaker is under consideration, the Speaker is entitled to vote on the resolution. Importantly, in this situation, the Speaker can vote in the first instance, not just in the event of a tie. Normally, the Speaker of the Lok Sabha votes only in the case of an equality of votes (casting vote), but when their own removal is being discussed, the Speaker has the right to participate in the vote from the beginning.
