A.
/etc/cron.d

B.
/var/spool/cron

C.
/var/spool/cron/crontable

D.

Explanation:
crontab: you are not authorized to use cron. Sorry.
This message means that either the user is not listed in the cron.allow file (if the file exists), or the
user is listed in the cron.deny file.
You can control access to the crontab command by using two files in the /etc/cron.d directory:
cron.deny and cron.allow. These files permit only specified users to perform crontab command
tasks such as creating, editing, displaying, or removing their own crontab files.
The cron.deny and cron.allow files consist of a list of user names, one user name per line.
