Answer: A

Explanation:

RAID 5 uses striping with parity and requires a minimum of three disks. It offers redundancy through the use of parity, and if one disk fails, the data can still be reconstructed from the remaining disks. It has a better storage-to-redundancy ratio compared to RAID 6, RAID 10, or RAID 50, making it the most suitable option in this scenario where maximizing storage is the main concern. RAID 5’s use of only one parity disk across the array means more of the total disk capacity is available for storage.
