Best answer
Right choice is (c) a daemon

For explanation I would say: cron is a daemon which runs on UNIX systems. It executes programs at regular intervals. It lets us to schedule jobs so that they can be scheduled repeatedly. It executes cron jobs created by the crontab. For example, a cron job can be scheduled for processing logs every evening.
