Answer: Amazon EC2 instance store

The correct answer is B, Amazon EC2 instance store. This storage type is ephemeral, meaning it is temporary and not persistent. When an Amazon EC2 instance is stopped or terminated, the data stored in the instance store is deleted and cannot be recovered. This is in contrast to Amazon EBS, which provides persistent block-level storage that remains intact even if the instance is stopped or terminated. Amazon EFS and Amazon S3 are not related to EC2 instance storage and are not ephemeral.
