The correct answer is tune2fs -c 1 /dev/sda1 because the command sets the maximum mount count (-c) to 1 for the filesystem on /dev/sda1, ensuring that fsck will be run the next time the filesystem is mounted. This is typically during the boot process. The option -C 0 sets the current mount count to 0, which is incorrect in this context because it does not schedule a check on the next boot. The -i flag is used for setting the interval between checks based on time, not on the number of mounts. The e2fsck -p /dev/sda1 executes a filesystem check, but does not schedule it for the next boot.
