Explanation

B (RAID 1 for OS): RAID 1 mirrors data across two drives, so if one OS drive fails, the other keeps the system running - satisfying Requirement 1. A (RAID 0 for OS) provides no redundancy and is eliminated immediately. C (RAID 1 for application data): RAID 1 mirroring ensures data availability even when drives fail, satisfying Requirement 3 better than RAID 5 (D), which can only tolerate a single drive failure and has slower write performance due to parity calculations. E (SSD drives for application data): SSDs deliver dramatically higher IOPS than SATA spinning disks (F), directly satisfying Requirement 2 for performance. G (single JBOD) offers no redundancy or fault tolerance at all.
