B Correct answer
Explanation

Striping (RAID 0) spreads data across multiple disks to improve performance through parallel read/write operations. By dividing data into blocks and writing them simultaneously to different disks, I/O bandwidth increases. Parity provides fault tolerance, mirroring provides redundancy, clustering is unrelated.
