Under ISA 240, as summarized in the Auditors' Fraud-Related Responsibilities chapter, if the auditor identifies or suspects fraud involving management, the auditor must communicate those suspicions to those charged with governance and discuss the nature, timing, and extent of audit procedures necessary to complete the audit. The manual also states that when fraud involving management or persons with significant internal control roles is identified, the auditor shall communicate these matters to those charged with governance on a timely basis. Reporting outside the entity may be required in some circumstances, but the auditor must first determine whether such a responsibility exists because confidentiality duties can apply. Therefore, the best immediate response in this scenario is to report the findings to those charged with governance.

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.
