The correct answer is D. No time limit.
There is no specific time limit for submitting a management audit report. The time limit may vary depending on the organization’s policies and procedures. However, it is important to submit the report as soon as possible after the audit is completed in order to ensure that any necessary corrective actions can be taken.
Option A is incorrect because 15 days is too short of a time limit to conduct a thorough audit and prepare a report. Option B is incorrect because 20 days is still too short of a time limit for most audits. Option C is incorrect because 30 days is a common time limit for submitting a management audit report, but it is not the only possible time limit.
