D Correct answer
Explanation

RAID 5 provides fault tolerance through distributed parity and excellent read performance through striping across multiple disks, making it ideal for read-intensive applications. RAID 0 has no fault tolerance. RAID 1 mirrors but has lower performance. RAID 3 has dedicated parity creating a bottleneck. RAID 5 balances performance, cost, and redundancy.
