The correct answer is option 2, the Speaker of Lok Sabha. The Speaker of Lok Sabha is responsible for deciding if a particular Bill is a Money Bill or not. A Money Bill is a type of bill that deals with financial matters, such as taxation, borrowing, or expenditure of the government. As per Article 110 of the Indian Constitution, a bill can be classified as a Money Bill if it contains only provisions related to matters such as imposition, abolition, alteration, or regulation of any tax, appropriation of money from the Consolidated Fund, or matters deemed incidental to these subjects. The Speaker`s decision on whether a bill is a Money Bill or not is final and cannot be challenged in a court of law.
