The correct option is "2 only." In the context of the Union Government, the Constitution mandates that no amount can be withdrawn from the Consolidated Fund of India without the authorization of Parliament, highlighting the principle of parliamentary control over public finances. In contrast, while the Department of Revenue plays a role in revenue collection and policies, the actual preparation of the Union Budget is the responsibility of the Ministry of Finance, specifically by the budget division under it. Additionally, disbursements from the Public Account do not require prior Parliamentary approval, as they are typically for transactions such as provident funds or other similar accounts that are held separately for specific purposes.
