Which three are valid directories for cron jobs to be run at known intervals?

A/etc/cron.hourly

B/etc/cron.daily

C/etc/cron.minutely

D/etc/cron.monthly

E/etc/cron.yearly

An alternative to editing the crontab is to place executable scripts into one of the following directories. The script will be run at the appropriate interval.

/etc/cron.daily

/etc/cron.weekly

/etc/cron.monthly
