Q24. Which of the following statements about UNIX signals is NOT correct?

AThe INT signal is sent by the terminal driver when one types the interrupt character (e.g. Ctrl-C), requesting termination of the current operation. BTERM is a request to terminate execution completely; the receiving process cleans up its state and exits. CQUIT is similar to TERM, except that it defaults to producing a core dump if not caught. DKILL is a blockable signal.
