Explanation
The correct answer is C: Deputy Speaker of the Lok Sabha.
If the Speaker of the Lok Sabha intends to vacate his or her office before the expiry of his or her term, he or she must send a resignation letter to the Deputy Speaker of the Lok Sabha. The Deputy Speaker then assumes the role of Acting Speaker until a new Speaker is elected.
It's important to note that the Speaker of the Lok Sabha is elected by the members of the Lok Sabha, and the position is held for the duration of the Lok Sabha's term, which is typically five years. However, the Speaker may resign from their position before the term is up, or they may be removed from their position through a vote of no confidence by the members of the Lok Sabha.
