Explanation:

- Article 112 of the Indian Constitution is indeed about the Union Budget. It mandates the government to present a statement of estimated receipts and expenditures, more commonly known as the Budget, for every financial year to Parliament.

- Option 1: Consolidated Fund of India - This is a fund to which all receipts are credited and from which all payments are made by the government of India, except those that are specifically charged to another fund.

- Option 2: Public Account - This consists of all other public money received by or on behalf of the government of India. Transactions here are not subject to parliamentary approval.

- Option 3: Union Budget - This is the annual financial statement reflecting the government's financial plan for the year, detailing expenditures and revenue. This corresponds to Article 112.

- Option 4: Contingency Fund - This fund is used by the President of India to meet unforeseen expenditures.
