No Money bill can be introduced in the Lok Sabha without the prior approval of the President. A Money bill is a type of legislation that solely deals with matters related to taxation, government spending, or borrowing. Since the President is the head of the state and exercises executive powers, their approval is required before introducing any Money bill in the Lok Sabha.

In option 1, the Vice-President does not have the authority to approve or disapprove Money bills. The Vice-President acts as the Chairperson of the Rajya Sabha and has limited executive powers.

In option 3, the Prime Minister also does not have the power to approve or disapprove Money bills. The Prime Minister is the head of the government and is primarily involved in policy-making and governance.

In option 4, the Finance Minister does not have the sole authority to approve or disapprove Money bills. The Finance Minister is responsible for presenting the annual budget and managing the finances of the country but does not have the power to approve Money bills.

Therefore, the correct answer is option 2, the President.
