B Correct answer
Explanation

In RAID systems, hard drives are redundant by design - multiple drives store the same data or parity information so that if one drive fails, data isn't lost and the system continues operating. Fans, NICs, and processors can be redundant in other contexts but RAID specifically protects against drive failure.
