A user is trying to create a PIOPS EBS volume with 4000 IOPS and 100 GB size. AWS does not allow the user to create this volume.
What is the possible root cause for this?

A. PIOPS is supported for EBS higher than 500 GB size
B. The maximum IOPS supported by EBS is 3000
C. The ratio between IOPS and the EBS volume is higher than 30
D. The ratio between IOPS and the EBS volume is lower than 50
