None of the above checkbox in Google Forms

I would like to create a multiple choice checkbox question in Google forms with a ‘None of the above’ option and validate that if that option is selected none of the other options is selected.

eg Choose your favourite fruits _ Apple _ Pear _ Orange _ Banana _ None of the above

I cant see how to perform that sort of validation using the built in validation options

Is there a way of performing such validation at data entry time?
