* 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.
