You are responsible for implementing a data retention policy for a large dataset stored in Azure Blob Storage. Which of the following approaches should you use to enforce the retention policy?
A
Use Azure Lifecycle Management to automatically move older blobs to a cooler storage tier based on their age.
B
Implement a custom script that periodically scans the blobs and moves the ones that exceed the retention period to a separate container for deletion.
C
Use Azure Event Grid to trigger a custom function that deletes the blobs that exceed the retention period.
D
Configure a soft delete policy for the blobs to prevent accidental deletion and implement a custom script to permanently delete the blobs that exceed the retention period.
