$id will have the same value for all your options.

So you might want to put name="answer" instead:

<input type="radio" name="answer" value="<?php echo $id?>-<?php echo $option2?>" />

On your result page $_GET['answer'] should then have the correct value.

You could send all the answers as hidden elements:

<input type="hidden" name="allanswers[]" value="Answer 1" />
<input type="hidden" name="allanswers[]" value="Answer 2" />
<input type="hidden" name="allanswers[]" value="Answer 3" />
<input type="hidden" name="allanswers[]" value="Answer 4" />
