A single file SnapRestore was performed a week ago from a snapshot other than the most recent. It has been noticed that the storage appliance is now taking longer to perform snapshot deletions. Choose from the following reasons which is the most likely cause of this problem.

A.
Snapshots that existed after the one used for the single file SnapRestore need to be manually deleted.

B.
Before a snapshot can be deleted, the active maps across all snapshots need to be checked for active blocks related to the file you restored.

C.
All of the snapshots created after you did the single file SnapRestore were deleted, and reserved inodes from the snapshots still exist.

D.
The SnapRestore schedule changed from weekly to hourly.
