Each OS process also runs a special thread called SCMN, which is basically an internallistener thread. All thread creation is routed through this thread.

NO B. The database listener does not spawn threads, instead the connection requests, handled by a dispatcher, are handed out to the spawning thread for the given instance. Each OS process running multiple Oracle processes also run an internal listener thread called SCMN. All thread creation is routed through this thread.
NO D. Each OS process also runs a special thread called SCMN that is basically an internal listener thread. All thread creation is routed through this thread.
Each multithreaded Oracle process has an SCMN thread.
E. The local listener may pass the request to an existing process which in turn will create a thread.
