What is the systemd journal stored?
The systemd journal is stored either persistently in /var/log/journal/ or in a volatile way in /run/log/journal/. The /var/log/journal/ directory is used to store journal files persistently across reboots, while /run/log/journal/ is used for volatile storage which is cleared on reboot.
agreed. Confirmed /var/log/journal for Ubuntu
C is correct. "...stores log data either persistently below /var/log/journal or in a volatile way below /run/log/journal..." - From system-journald.service(8) man pages
