Hello @GaryP056 ,
The thank you page of the poll block can't be edited at this time, and there isn't really anything else in the system that would really work for handling trivia and giving responses for specific choices.
As a potential workaround, you could setup a couple of custom landing pages, one for the correct response and the other for the incorrect responses. Then you could add a text block with your trivia description / question in your email, add buttons for the potential responses, and then link the buttons to the corresponding custom landing page's share URLs. While this would ultimately blend with your regular click reporting - it would at least allow you more control over the answer selection response.
