B Correct answer
Explanation

PMON (Process Monitor) dynamically registers the instance with the listener when there's no static registration in listener.ora. When you start the listener with 'lsnrctl start', it starts successfully, and PMON automatically registers the running instance with it. This is dynamic registration - the instance will be registered despite no listener.ora entry. CJQn is the job queue process, irrelevant here.
