The traditional way to exit and LISP system is to enter A. quit B. exit C. bye D. ok E. None of the above

The correct answer is B. exit.

The traditional way to exit a LISP system is to enter the command exit. This will cause the system to terminate and return to the operating system.

The other options are incorrect. The command quit will also cause the system to terminate, but it is not the traditional way to do so. The command bye is not a valid command in LISP. The command ok is used to confirm a prompt, but it will not cause the system to terminate.

Here is an example of how to use the exit command to exit a LISP system:

user> (exit)
Goodbye.

The system will then terminate and return to the operating system.
