Explanation RAID 1+0 (also known as RAID 10) combines RAID 1 (mirroring) and RAID 0 (striping) to provide both performance and redundancy. This means that data is simultaneously copied (mirrored) onto multiple disks (RAID 1) and then striped (RAID 0) across the mirrored arrays. This offers the best of both worlds by providing both high performance and data protection.

Option A (Striping) does not involve mirroring and does not provide any data redundancy.

Option B (Mirroring) is only RAID 1 and does not offer any performance benefits.

Option C (Striping with parity) is RAID 5, not RAID 1+0, and does not offer the same level of performance or data protection.
