B Correct answer
Explanation

When you start the listener with LSNRCTL> START without specifying a listener name, it starts the default listener named LISTENER. The output shows the listener starting but doesn't explicitly name it - you need to know the default. TNSLSNR (option A) is the listener executable name, not the listener instance name. LOCAL_LISTENER and DEFAULT_LSRN (options C and D) are not valid default names.
