How can I end if wrong answer?

I want to stop the survey on a qualifying question and offer a nnote that says You are not qualified to take this survey.

Hi,

Thank you for contacting us.

I think this is possible to do, you can use a hidden text and show it only if the selected question is wrong, also you can hide the submit button or hide other fields, you can do it using conditions in your form, refer to these guides in order to get more information about conditions :
