The internal audit plan must remain dynamic and responsive to changes in circumstances. If a key project is postponed, the CAE should amend the audit plan, reallocate resources appropriately, and inform the board and senior management for review and approval. This ensures transparency and continued alignment with organizational risks.

Option A improperly shifts audit resources under management’s direction. Option B may be considered but requires board and management approval through an amended plan. Option D leaves resources idle, which is inefficient.
