A Company Has a Centralized Group of Users with Large

A company has a centralized group of users with large file storage requirements that have exceeded the space available on premises. The company wants to extend its file storage capabilities for this group while retaining the performance benefit of sharing content locally. What is the MOST operationally efficient AWS solution for this scenario?

A) Create an Amazon S3 bucket for each users. Mount each bucket by using an S3 file system mounting utility.
B) Configure and deploy an AWS Storage Gateway file gateway. Connect each user's workstation to the file gateway.
C) Move each user's working environment to Amazon WorkSpaces. Set up an Amazon WorkDocs account for each user.
D) Deploy an Amazon EC2 instance and attach an Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS volume. Share the EBS volume directly with the users.
