Explanation

RAID 1 (mirroring) duplicates the same data across two drives simultaneously. If one drive fails, the other contains an identical copy of all data, so operations continue without interruption. This provides full fault tolerance with two drives. RAID 0 (A) stripes data across drives for performance but provides no redundancy - if either drive fails, all data is lost. RAID 5 (C) provides fault tolerance using parity distributed across drives, but requires a minimum of three drives. RAID 6 (D) can tolerate two simultaneous drive failures but also requires a minimum of four drives. With only two drives available, RAID 1 is the correct and only viable fault-tolerant option.
