Answer is A However.... This question is unlikely to be asked now as "Amazon EBS Multi-Attach" now lets up to 16 Linux servers connect to an EBS volume. "https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volumes-multi.html" Amazon EBS Multi-Attach enables you to attach a single Provisioned IOPS SSD (io1 or io2) volume to multiple instances that are in the same Availability Zone. You can attach multiple Multi-Attach enabled volumes to an instance or set of instances. Each instance to which the volume is attached has full read and write permission to the shared volume. Multi-Attach makes it easier for you to achieve higher application availability in clustered Linux applications that manage concurrent write operations.

A is my take. In order for the EC2 instances to access it concurrently, a file share system of some sort is the best option from the provided choices
