What are the advantages of RAID 5 over RAID 1?

A. The recovery/rebuild time on RAID 5 would be much longer than on RAID 1. Recalculation of the lost data is necessary in RAID 1.
B. The recovery/rebuild time on RAID 1 would be much longer than on RAID 5. No recalculation of the lost data is necessary in RAID 1.
C. A small amount of storage capacity is lost by storing the parity bits (RAID 5), but it is much less than it would be if the entire array were mirrored (RAID 1).
D. A small amount of storage capacity is lost by storing the parity bits (RAID 1), but it is much less than it would be if the entire array were mirrored (RAID 5).
