Answer: Establish an Amazon EFS and mount it on web servers.
The correct answer is C. Amazon Elastic File System (Amazon EFS) is a fully managed file storage service that is designed to be mounted on multiple instances, allowing the Linux-based web servers to access a shared file system without any need to modify the application. Option A (Amazon S3) and B (Amazon CloudFront with S3) do not provide the necessary functionality for a shared file system environment required by a typical web server. Option D (Amazon EBS) cannot be mounted on multiple instances simultaneously, which makes it unsuitable for this scenario.
