Option 1 states that the Speaker of the Lok Sabha has no right to vote in general circumstances. This means that the Speaker cannot vote under any circumstances while presiding over the proceedings of the Lok Sabha.

Option 2, the correct answer, states that the Speaker of the Lok Sabha has the right to vote only in case of a tie. This means that if there is a tie on a particular issue being voted upon in the Lok Sabha, the Speaker can cast a vote to break the tie.

Option 3 states that the Speaker of the Lok Sabha has the right to vote like other members of the House. This is not correct as the Speaker, while presiding over the proceedings, does not vote unless there is a tie.

Option 4 states that the Speaker of the Lok Sabha has the right to vote only once during the term of the House. This is not correct as the Speaker can vote in case of a tie, irrespective of the number of times it occurs during their term.

Therefore, the correct answer is option 2.
