Sectors in the RAID volume and on individual disks are indicated as above. Stripe diskGiven the following operations on the RAID 4 volume, translate them to the corresponding read or write operations, giving type (read or write), disk number, LBA, and length foreach operation. There are several ways in which (B) and (C) may be performed; for each give the one resulting in the fewest resulting read and write operations.read(LBA = 3,length 12) write(LBA = 3, length = 12) write(LBA = 24, length = 8) Again, please specify an exact sequence of disk read and write operations. Note that this question hasmultiple correct answers, each of which can be expressed multiple ways.

On the RAID 4 Volume to the corresponding read or write operations, we need to consider the layout…
