The correct answer is: A. Directors.
The cost auditor is an independent auditor who is appointed by the directors of a company to audit the company’s cost accounts. The cost auditor’s report is addressed to the directors and is intended to provide them with an independent opinion on the accuracy and reliability of the company’s cost accounts.
The cost auditor’s report is not intended for the shareholders or the managers of the company. The shareholders are not directly involved in the management of the company and do not have a need for the cost auditor’s report. The managers of the company are responsible for the preparation of the cost accounts and are therefore in a position to assess their own accuracy and reliability.
The Company Law Board is a government body that is responsible for regulating companies in India. The Company Law Board does not have any role in the appointment or reporting of cost auditors.
