Internal Auditor ' s Role in Fraud Risk Management:

Internal auditors are not directly responsible for establishing or maintaining anti-fraud controls (Option D). This responsibility lies with management.

They are also not responsible for obtaining reasonable assurance that financial statements are free of fraud (Option A). This is the role of external auditors.

Oversight of management ' s fraud risk actions (Option B) is primarily a governance role, not the auditor ' s direct responsibility.

Internal auditors focus on identifying and assessing fraud risks, evaluating controls, and recommending further action when necessary.

Conclusion:Option C aligns with the internal auditor ' s responsibilities as per the standards outlined in the ACFE ' s fraud risk management framework.
