The correct option is C Only 2, 3 & 4
The Estimates Committee has 30 members and all these members are from Lok Sabha.
There is no Rajya Sabha member in Estimates Committee. The members are elected by Lok Sabha members from amongst themselves every year by principles of proportional representation by means of a single transferable vote, so that all parties get due presentation in it. A minister cannot be elected as member / Chairman of estimates committee. The chairman is appointed by the Speaker and chairman is always from ruling party or coalition.
This committee tries to report economy and efficiency in expenditures. It suggests what changes in policy or administrative framework can be done and what alternative policies can be considered to bring economy and efficiency. Due to this reason, this committee is also called ‘continuous economy committee’. The works of this committee continue throughout the year and it keeps reporting to the house as examination proceeds.
