Dedup and Compression requires all flash. RAID 5 satisfies all the requirements, but needs 2 extra hosts to support FTT=2

B for sure..due to maintaining compliance (RAID 6) otherwise A will work but will not be complaint with Storage Policy (RAID 5 minimum 4 hosts with 1 FTT) and hence adding extra host will allow to host be lost but means will be non-complaint
