Suggested answer: C

Explanation:

RAID 5 offers both disk redundancy and maximum usable disk capacity by using block-level striping with parity. RAID 5 allows one drive to fail while still retaining data, and it uses only one disk's worth of space for parity, maximizing the usable capacity.

RAID 5 (Answer C): Provides redundancy with only one disk's space used for parity, maximizing storage.

RAID 0 (Option A): Provides no redundancy; if one drive fails, all data is lost.

RAID 1 (Option B): Mirrors data, so redundancy is provided, but only half the capacity is usable.

RAID 10 (Option D): Combines RAID 1 and 0 for high performance and redundancy but requires half the disk space for mirroring.
