A.Allows the mirror partitions to spread across a maximum number of disks.
B.Allows the copy of a partition to be on the same physical volume as the mirrored partition.
C.Prevents partitions allocated to one logical volume mirror from sharing a physical volume with partitions from another logical volume mirror.
D.Forces copies of logical partitions to be housed on different physical volumes， while allowing a single physical volume to be shared by logical volume mirrors.
