B Correct answer
Explanation

Mirroring (RAID 1) provides fault tolerance by duplicating data on paired disks, allowing continued operation with no performance degradation when one drive fails. Striping has no fault tolerance, parity adds performance overhead during rebuild, and clustering is unrelated.
