Which one of the following duties is NOT performed by the Comptroller and Auditor General of India ?

The Comptroller and Auditor General (CAG) audits and reports on expenditure from the Consolidated Fund of India as a constitutional duty [1]. It is also required to audit transactions relating to Contingency Funds and Public Accounts, as well as trading, manufacturing, profit-and-loss accounts and related balance sheets kept in government departments [2]. However, the CAG in India functions effectively only as an auditor and does not exercise the traditional ‘comptroller’ role of controlling the receipt and issue of public money or ensuring that all public revenue is lodged in the exchequer; that control rests with administrative departments and accounting authorities, while the CAG performs post facto audit [3].
