RAID Level Matching - Explanation

Note: The question appears to be missing the target RAID level labels (the left-side drop zones). Based on the descriptions, here is what each item maps to and why:

Item 1 → RAID 6

"two sets of parity data are distributed across all drives"

RAID 6 extends RAID 5 by writing two independent sets of parity (double parity) striped across all drives. This requires a minimum of 4 drives and can survive the simultaneous failure of any 2 drives. No other common RAID level distributes two parity sets.

Item 2 → RAID 1 (or RAID 10)

"the ability to lose up to 50% of available drives"

RAID 1 (mirroring) duplicates every drive, so exactly half the drives are redundant copies. You can lose one drive in every mirrored pair - up to 50% of total drives - and still have full data. This is also true of RAID 10, but the "up to 50%" phrasing is the classic descriptor for RAID 1.

Item 3 → RAID 5

"protects against the failure of any one drive in the array"

RAID 5 uses single distributed parity across a minimum of 3 drives. It tolerates exactly one drive failure - no more. This is its defining characteristic and the most commonly tested fact about RAID 5.

Item 4 → RAID 10

"a maximum of one drive from each of the RAID groups can fail without loss of data"

RAID 10 (1+0) combines mirrored pairs (RAID 1) that are then striped (RAID 0). Each RAID 1 group can lose one of its two drives safely. The phrase "each of the RAID groups" is the key signal - this describes a nested/hybrid array, not a flat RAID level.
