B Correct answer
Explanation

Mirroring (RAID 1) provides fault tolerance through redundancy without performance degradation during a drive failure. Since both disks have identical data, reads continue normally from the surviving disk. Parity RAID (5/6) requires reconstruction and slows down during failure.
