Everything looks OK in your database. :/

As Brooks said, run Suspect File Versions and make sure all your files come out as default.

edit: whoops, posted after you. What version are you running and how long have you had this issue?

What is in the source code? It will be something like this:

<div id="polloptions" class="blockrow">
                 <ul class="checkradio group">
                      <li><label for="rb_optionnumber_1"><input type="radio" name="optionnumber" value="1" id="rb_optionnumber_1" tabindex="1" /> Yes</label></li>
   <li><label for="rb_optionnumber_2"><input type="radio" name="optionnumber" value="2" id="rb_optionnumber_2" tabindex="1" /> NO</label></li>
                  </ul>
             </div>
