What is the possible root cause for this?

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.
The ratio between IOPS and the EBS volume is higher than 30

B.
The maximum IOPS supported by EBS is 3000

C.
The ratio between IOPS and the EBS volume is lower than 50

D.
PIOPS is supported for EBS higher than 500 GB size

Explanation:
A provisioned IOPS EBS volume can range in size from 10 GB to 1 TB and the user can provision up to 4000
IOPS per volume. The ratio of IOPS provisioned to the volume size requested should be a maximum of 30; for
example, a volume with 3000 IOPS must be at least 100 GB.
