Correct answer & explanation
✓
Lifecycle management policy
A lifecycle management policy can automatically delete blobs based on age. Option A is wrong because Azure Policy enforces compliance but does not delete. Option C is wrong because Azure Blob Storage inventory provides reports but does not delete. Option D is wrong because Azure Purview scopes metadata and data discovery, not lifecycle management.
