Option 1 is the correct answer. A Money Bill passed by the Lok Sabha can be held up by the Rajya Sabha for a maximum of two weeks.

To understand this, we need to know the role and powers of the two houses of the Indian Parliament. The Lok Sabha is the lower house and has the power to introduce and pass Money Bills. The Rajya Sabha is the upper house and has the power to review and suggest changes to Money Bills, but it cannot block or delay the passage of a Money Bill.

However, there is a provision in the Constitution that allows the Rajya Sabha to hold up a Money Bill for up to 14 days. During this time, the Rajya Sabha can discuss and suggest amendments to the bill. After the two-week period, if the Rajya Sabha does not pass the bill or suggest any amendments, it is considered to have been passed by both houses.

Therefore, the correct answer is that a Money Bill passed by the Lok Sabha can be held up by the Rajya Sabha for a maximum of two weeks.
