RAID 0 (striping) provides high data throughput and I/O performance by distributing data across multiple disks. This configuration is suitable for SAP HANA workloads that require high performance and low latency

You don't need to configure any redundancy level using RAID volumes since Azure block storage keeps three images of a VHD. https://learn.microsoft.com/en-us/azure/sap/workloads/hana-vm-operations-storage

Selected Answer: B

Basically, RAID0 is not recommended for any enterprise DB system. The best throughout is RAID5 here. RAID10 is better.
