Process monitor (PMON) The process monitor performs process recovery when a user process fails. PMON is
responsible for cleaning up the cache and freeing resources that the process was
using. PMON also checks on the dispatcher processes (described later in this table)
and server processes and restarts them if they have failed.

The process monitor (PMON) monitors the other background processes and performs process recovery when a server or dispatcher process terminates abnormally. PMON is responsible for cleaning up the database buffer cache and freeing resources that the client process was using. For example, PMON resets the status of the active transaction table, releases locks that are no longer required, and removes the process ID from the list of active processes.

In releases before Oracle Database 12c, PMON performed the listener registration.

Should be A, D instead of C because C is now handled by LREG process in 12c.
