Amazon Elastic File System (Amazon EFS) and Amazon FSx offer which type of storage?

Explanations:

Amazon EFS and Amazon FSx both provide file storage, allowing users to store and access files using a file system interface.

Object storage, like Amazon S3, is used for storing unstructured data as objects, not as files or file systems.

Block storage, such as Amazon EBS, is used for low-level data storage in the form of blocks, not file systems.

Instance store is temporary storage tied to EC2 instances, not a managed file or block storage service.
