The correct answer is option 3, the Estimates Committee. The Estimates Committee is a parliamentary committee that examines the estimates of expenditure presented by the government. It is responsible for the scrutiny and assessment of the budgetary proposals put forth by the government.

Option 1, the Public Accounts Committee, is another important committee of the Parliament. It examines the auditor`s report on the accounts of the government and ensures that public funds are utilized efficiently and effectively.

Option 2, the Committee on Public Undertakings, is responsible for evaluating the functioning of public sector undertakings and assessing their performance.

Option 4, the Departmentally Related Standing Committee (DRSC) on Finance, is a committee that scrutinizes the budget and other financial matters related to various departments and ministries. It is composed of members from both the Lok Sabha and the Rajya Sabha.

In summary, the Estimates Committee is the only committee mentioned in the options that does not have any members from the Rajya Sabha. The other committees mentioned have members from both the Lok Sabha and the Rajya Sabha.
