Why each option

Fibre Channel and SAS hard drives, commonly used in enterprise environments for high performance, typically have rotational speeds of 10,000 RPM and 15,000 RPM.

A3400 RPM

3400 RPM is not a standard rotational speed for any modern hard drives, especially not high-performance enterprise drives.

B5400 RPM

5400 RPM is a common rotational speed for consumer-grade SATA hard drives, typically found in desktop computers and external storage, not high-performance Fibre Channel or SAS drives.

C7000 RPM

7000 RPM is not a standard rotational speed for hard drives; common speeds are 5400, 7200, 10000, and 15000 RPM.

D10.000 RPMCorrect

10,000 RPM (revolutions per minute) is a common high-performance rotational speed for enterprise-grade SAS and Fibre Channel hard drives, offering significantly faster data access times than consumer-grade drives.

E15,000 RPMCorrect

15,000 RPM is the highest common rotational speed for enterprise SAS and Fibre Channel hard drives, providing the fastest possible mechanical disk performance, crucial for applications requiring extremely low latency and high I/O operations per second (IOPS).
