Question

Explanation
The boot error indicates that the /data filesystem failed to mount, causing a systemd dependency failure and dropping the system into emergency mode. The /etc/fstab file defines which filesystems are mounted at boot and their options. A wrong device path, UUID, or mount option in /etc/fstab for the /data entry would cause exactly this error. Option A (/etc/mtab) is a runtime file reflecting current mounts. Option B (/dev/sda) is a device node, not a config file. Option D (/etc/grub.conf) controls the bootloader, which is unrelated to filesystem mounting failures.
