B "Physical storage is allocated to the host “on-demand” from a shared pool of physical capacity. A shared pool consists of physical disks. A shared pool in virtual provisioning is analogous to a RAID group, which is a collection of drives on which LUNs are created. <<Similar to a RAID group, a shared pool supports a single RAID protection level>>. However, unlike a RAID group, a shared pool might contain large numbers of drives. Shared pools can be homogeneous (containing a single drive type) or heterogeneous (containing mixed drive types, such as flash, FC, SAS, and SATA drives). Information Storage and Management . Wiley.

Correct: B A shared pool in virtual provisioning is analogous to a RAID set, which is a collection of drives on which LUNs are created. Similar to a RAID set, a shared pool supports a single RAID protection level.
