Answer - C - A RAID-5 volume provides the ability to recover from the failure of a single hard drive.

Key Takeaway: RAID 5 stripes both data and parity information across three or more drives. It removes the bottleneck that the dedicated parity drive represents, thus improving write performance slightly and allowing better parallelism. The performance of a RAID 5 array can be adjusted by trying different stripe sizes until one is found that is well-matched to the application.
