Well I just went ahead and did it. I'm not sure if it's the best way, but it's a way. I used server side. I positioned little crosses and ticks beside the appropriate answers using relative positioning.
I then set them to Visible="False" (I'm using asp:Image tags).
I then just checked the logic on the associated c# file under the submit button clicked method and set the appropriate crosses and or ticks to visible.
