Explanation:
The question pertains to the initial permissions that can be granted to the group root of an Amazon Elastic File System (EFS) file system. According to the provided information, the correct answer is B. read-execute. This is because Amazon EFS allows for specific permission modes when a file system and mount targets are created within a Virtual Private Cloud (VPC). The initial permissions granted are read-write-execute permissions to the owner (root), read-execute permissions to the group root, and read-execute permissions to others. This setup enables the file system to be mounted locally on Amazon Elastic Compute Cloud (EC2) instances and allows users to access the file system with the appropriate permissions. The reference to the AWS documentation further supports this configuration of permissions.
