正解:C

A change in organizational structure with significant impact to business processes may require a revision of the BCP and a new test plan to validate its adequacy. The lack of a test plan for the BCP for two years indicates a high risk of failure in the event ofa disaster or disruption.
Therefore, this should be the auditor's greatest concern among the given options. References:
