Which RAID level does not use parity data?

Explanation:
Parity data is extra information used to rebuild data after a disk failure. RAID levels that include parity store this parity so you can recover from a drive failure without restoring from backup. The levels that use parity are RAID 5 and RAID 6. The levels that do not use parity are RAID 0, which stripes data for performance with no redundancy, and RAID 1, which mirrors data on another disk for redundancy without parity blocks. So, parity is absent in these configurations, meaning the question as written has two valid options rather than one.
