The correct answer is (a), Comptroller and Auditor General of India.
The Comptroller and Auditor General of India (CAG) is an independent constitutional authority of India, responsible for auditing the accounts of the central and state governments, as well as of public sector undertakings. The CAG is appointed by the President of India, on the advice of the Prime Minister, for a term of six years or until he/she attains the age of 65 years, whichever is earlier. The CAG can only be removed from office on the recommendation of a special committee consisting of the Prime Minister, the Leader of the Opposition in the Lok Sabha, and the Chief Justice of India.
The CAG is not subject to the control of any other authority, and his/her reports are submitted directly to the Parliament of India. The CAG has the power to investigate all matters relating to the receipt and expenditure of public money, and to report on any irregularities or deficiencies that he/she finds. The CAG’s reports are considered to be very important, and they have often led to major changes in government policies and procedures.
The other options are incorrect because:
- The Chief Election Commissioner (CEC) is appointed by the President of India, on the recommendation of the Election Commission of India. The CEC holds office for a term of six years or until he/she attains the age of 65 years, whichever is earlier. The CEC can only be removed from office on the recommendation of a special committee consisting of the Prime Minister, the Leader of the Opposition in the Lok Sabha, and the Chief Justice of India.
- The Speaker of the Lok Sabha is elected by the members of the Lok Sabha. The Speaker holds office for the duration of the Lok Sabha. The Speaker can only be removed from office by a resolution passed by a majority of the members of the Lok Sabha.
- The Attorney General of India is appointed by the President of India, on the advice of the Prime Minister. The Attorney General holds office during the pleasure of the President. The Attorney General can be removed from office by the President, at any time, without assigning any reason.
