Answer: Amazon EFS

The correct answer is D, Amazon Elastic File System (Amazon EFS). Amazon EFS is a fully managed NFS file system that can be easily mounted on AWS compute resources. It provides a scalable, elastic file storage that grows and shrinks automatically as you add and remove files, without the need for manual storage provisioning or management. The other options are not suitable for this requirement: A (Amazon EBS) is a block storage service for EC2 instances, B (AWS Storage Gateway Tape Gateway) is for backup and archive purposes, and C (Amazon S3 Glacier Flexible Retrieval) is a cold storage service with retrieval options.
