A . Yes, they do but only if they are detached from the instance.
B . No, you cannot attach EBS volumes to an instance.
C . No, they are dependent.
D . Yes, they do.

Answer: D

An Amazon EBS volume behaves like a raw, unformatted, external block device that you can attach to a single instance. The volume persists independently from the running life of an Amazon EC2 instance.
