Should be D: While restoring the LUNs, the system automatically creates a backup snapshot associated with the current point-in-time which allows administrators to reverse this operation and return the resource to the point-intime immediately before the snapshot was restored.

Restore Restoring a snapshot reverts its associated parent resource to the point-in-time at which the snapshot was taken. For LUNs, file systems, and VMware Datastores, this is the individual resource. For consistency groups, all LUNs in the group are restored to the single point-in-time that is associated with the snapshot. While restoring the LUNs, the system automatically creates a backup snapshot associated with the current point-in-time which allows administrators to reverse this operation and return the resource to the point-in-time immediately before the snapshot was restored. Before restoring a snapshot, Dell EMC recommends that you quiesce the application that is running on the production host, and then flush the host cache to prevent data corruption during the restore operation.
