Will AWS create the volume?

A user is trying to create a PIOPS EBS volume with 8 GB size and 200 IOPS. Will AWS create the volume?

A.
Yes, since the ratio between EBS and IOPS is less than 30

B.
No, since the PIOPS and EBS size ratio is less than 30

C.
No, the EBS size is less than 10 GB

D.
Yes, since PIOPS is higher than 100

Explanation:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html
An io1 volume can range in size from 4 GiB to 16 TiB and you can provision up to 20,000 IOPS per volume. The ratio of
IOPS provisioned to the volume size requested can be a maximum of 30; for example, a volume with 3,000 IOPS must
be at least 100 GiB. You can stripe multiple volumes together in a RAID configuration for larger size and greater
performance.
