Selected Answer: A

Answer A is the right one. Adaptative RAID-5 will work with 3 to 5 hosts. So the 6th host can be definitely lost. B : vSphere HA does not manage the storage objects C : the VMs are protected (RAID-5=FTT 1), so their data is still available D : the degraded state is displayed only for a disk or controller permanent failure. Losing on e host will mark the component as absent.
