A company wants to store and retrieve files in Amazon S3 for its existing on-premises applications by using industry-standard file system protocols. Which AWS service will meet these requirements?
A. AWS DataSync: is a service for transferring large amounts of data between on-premises storage and Amazon S3, but it is designed for data movement, not for providing real-time file system access
B. AWS Snowball Edge: Device that provids large volumes or edge computing offline data transfer capabilities. Not for access to S3
C. Amazon S3 File Gateway: Allows storing and retrieving files in Amazon S3 using industry-standard file protocols. It acts as a bridge between your on-premesis file-based applications and Amazon S3 object storage
D. AWS Transfer Family: Fully managed support for SFTP, FTPS and FTP. provides fully managed support for file transfers directly into and out of Amazon S3 or Amazon EFS. Supports file transfer protocols, not file system protocols
The Amazon S3 File Gateway enables you to store and retrieve objects in Amazon Simple Storage Service (S3) using file protocols such as Network File System (NFS) and Server Message Block (SMB). Objects written through S3 File Gateway can be directly accessed in S3.
C. Amazon S3 File Gateway
A S3 File Gateway simplifies file storage in Amazon S3, integrates to existing applications through industry-standard file system protocols, and provides a cost-effective alternative to on-premises storage. It also provides low-latency access to data through transparent local caching. A S3 File Gateway manages data transfer to and from AWS, buffers applications from network congestion, optimizes and streams data in parallel, and manages bandwidth consumption.

Amazon S3 File Gateway – Amazon S3 File Gateway supports a file interface into Amazon Simple Storage Service (Amazon S3) and combines a service and a virtual software appliance. By using this combination, you can store and retrieve objects in Amazon S3 using industry-standard file protocols such as Network File System (NFS) and Server Message Block (SMB).
C. Amazon S3 File Gateway
Amazon S3 File Gateway provides NFS and SMB access to objects stored in Amazon S3. It enables existing on-premises applications to access data in Amazon S3 as if they were accessing a file system, using standard file system protocols. This makes it an ideal solution for integrating on-premises applications with Amazon S3 storage.

Our solution uses File Gateway to provide on-premises applications low-latency access to data stored in Amazon S3. Because File Gateway uses industry standard storage protocols such as NFS and SMB, customers can reduce, or even eliminate, on-premises storage for their reports without changing the applications that generate those reports.
AWS Transfer Family offers fully managed support for the transfer of files over SFTP, AS2, FTPS, and FTP directly into and out of Amazon S3 or Amazon EFS. You can seamlessly migrate, automate, and monitor your file transfer workflows by maintaining existing client-side configurations for authentication, access, and firewalls—so nothing changes for your customers, partners, and internal teams, or their applications.

I could see either C or D as an answer here, but this is literary the entire purpose of this service so it seems to me like the "best" answer
Im gonna actually change my answer after thinking about it for a while. Because the file gateway is a configuration for the AWS storage gateway, which is a service that connects on-premise datacenters to the cloud. They both use common protocols, but the transfer family doesnt really have anything to do with on-premie to cloud migration or intergration.
C. Amazon S3 File Gateway
Q: What is Amazon S3 File Gateway?
Amazon S3 File Gateway is a configuration of the AWS Storage Gateway service that provides your applications a file interface to seamlessly store files as objects in Amazon S3, and access them using industry standard file protocols.
"Amazon S3 File Gateway provides a seamless way to connect to the cloud in order to store application data files and backup images as durable objects in Amazon S3 cloud storage. Amazon S3 File Gateway offers SMB or NFS-based access to data in Amazon S3 with local caching. It can be used for on-premises data-intensive Amazon EC2-based applications that need file protocol access to S3 object storage."
