C Correct answer
Explanation

Mirroring is correct because it writes identical data to two disks simultaneously, creating an exact copy for redundancy. Parity uses mathematical schemes across multiple disks, striping spreads data across disks without redundancy, and clustering refers to multiple servers working together, not disk-level redundancy.
