Hi @Thauck yes this is quite possible but you need to use Microsoft Flow to do it, it's not possible within Forms itself. Within Flow you would have a trigger for "When a new response is submitted", the first action is then to "Get response details" and you'd then have what's called a Switch case action which would look at the option 1 response. If it was A, it would send the email to person A, if it was B it would send it to person B and so on. You could have up to 25 (I think) possible cases here.
Let me know if you need screenshots of how this works.
