Correct answer: D. Crontabs for individual users are not stored.
Explanation
cron is indeed UNIX's standard time-based job scheduler (statement 1, true); it is started once at boot and runs for as long as the system is up (statement 2, true); and it works precisely by reading crontab configuration files that pair commands with their schedule (statement 3, true). Per-user crontabs, however, very much are stored by the system, typically as one file per user under a spool directory such as /var/spool/cron/crontabs/<user>, so claiming they are "not stored" is false — statement (iv) is the incorrect one.More Software Engineering questions
