The mount -a command reads the /etc/fstab file and mounts all file systems that are listed with the auto option, but are not currently mounted. So, the correct option is: D. It ensures that all file systems listed with the option auto in /etc/fstab are mounted. Here's how this command works: The mount command is used to mount file systems. The -a option specifies that all file systems listed in /etc/fstab should be mounted. The file systems that are listed with the auto option in /etc/fstab are mounted, while the file systems listed with the noauto option are not mounted.
