The audit report of the Comptroller and Auditor General of India is examined by

1. A

   Public Accounts Committee

   Public Accounts Committee. This option claims that the audit report of the Comptroller and Auditor General of India is examined by the Public Accounts Committee, which is the correct parliamentary body mandated for this financial oversight function.

2. B

   Public Undertaking Committee

   Public Undertaking Committee. This option suggests that the audit report is examined by the Committee on Public Undertakings, which specifically examines the reports and accounts of public sector undertakings rather than the overall CAG audit reports.

3. C

   The Estimates Committee

   The Estimates Committee. This option states that the audit report goes to the Estimates Committee, which instead examines estimates included in the budget and suggests economies in public expenditure, not post-audit reports.

4. D

   None of the above

   None of the above. This option claims that none of the listed committees examine the CAG report, which is incorrect because the Public Accounts Committee is explicitly tasked with this constitutional responsibility.

Summary. Official key is (a) Public Accounts Committee. The Comptroller and Auditor General submits audit reports relating to the accounts of the Union to the President, who places them before both Houses of Parliament. These reports are then thoroughly examined by the Public Accounts Committee. Candidates often confuse this with the Estimates Committee, which deals with budget estimates rather than post-expenditure audit reports. Therefore, option (a) is the only correct and comprehensive choice among the given alternatives.
