A jail in fail2ban is a filter definition and a set of one or more actions to take when the filter is matched. It essentially defines what should be monitored (filtered) and what actions should be taken (bans or other actions) when suspicious patterns are detected in log files.
C is correct! The file is called jail.conf because remote hosts are placed in a “jail” due to suspicious activity. As with a real jail, the intent is to let the host out of jail after a specific period of time. https://www.redhat.com/sysadmin/protect-systems-fail2ban
