I'm trying to get a drag and drop that has only one target area and 4 options to show a green checkmark when the correct option is chosen otherwise for all else, show the wrong (red) x. I can't get the wrong X to show. It works fine if each drag item has a target spot, but not if there is only 1 target spot and only one correct answer out of 4. So far I've tried everything I know. Any suggestions. Please see attached.
