which RAID implementation?

Creating one large disk by using several disks is used in which RAID implementation?

A.
RAID level 0

B.
RAID level 1

C.
RAID level 2

D.
RAID level 3

Explanation:
RAID level 0 creates one large disk by using several disks. This
process is called striping, as it stripes data across all disks. This improves
performance, but lessens fault tolerance by making the entire data volume unusable
if one of the disks fails.
