Complete answer:
Comptroller and Auditor General of India is that the authority liable for external and internal audits of the expenses of the National and state governments. It's popularly referred to as the CAG of India. Now let’s see who appoints CAG,
The chief justice or judge presides over the Court's public sessions and also presides over the Court's private conferences, where the justices decide what cases to listen to and the way to vote on the cases they need heard. CJI doesn't appoint CAG.

The Minister of Finance is the head of the Ministry of Finance of the government of India. One among the senior-most offices within the Union Cabinet, the minister of finance is appointed by the president.
The Comptroller and Auditor General is appointed by the President of India and may be removed from office within the manner and on the grounds that a Judge of the Supreme Court is removed.
