A.
RAID 1

B.
RAID 3

C.
RAID 4

D.
RAID 5

Explanation:
Answer D is correct; RAID 5 involves the use of block level striping, for performance purposes, and parity for reliability purposes. The parity, in the case of RAID 5, is distributed across all drives rather than being dedicated.

Incorrect Answers and Explanations: A, B, and C: Answers A, B, and C are incorrect. RAID 1 uses disk mirroring rather than parity, and does not leverage striping. Both RAIDs 3 and 4 leverage striping for the performance increase, but RAID 3 uses byte level while RAID 4 uses block level striping. Both RAIDs 3 and 4 use a dedicated parity disk rather than a distributed one as is used by RAID 5.
