In my report, I had them in a group. And then in report's Detail_Format event, I said if the group value was 1 then Box A Label was Bold, and Box B and Box C was not visible. At least in this way the selected answer was the only on visible in the report. If no selection was made, then all were Visible, but could just as easily show up as invisible by default till a selection was made.
