An internal auditor finds inconsistencies in a risk area that needs immediate attention.

Comprehensive and Detailed Explanation:

Per IIA Standard 2440 – Disseminating Results, if an engagement reveals issues that require urgent management action, the auditor should issue an interim communication rather than waiting for the final report. This ensures that management is alerted promptly to risks that could materially affect the organization. Option A is not appropriate because developing corrective action plans is management’s responsibility, not audit’s. Option B, direct reporting to regulators, bypasses governance channels unless laws require immediate external reporting. Option C (risk assessment) is part of planning but does not satisfy the urgency of immediate communication. The best response is Option D: communicate the critical inconsistencies promptly to senior management through an interim report, allowing them to take timely corrective measures.
