The option "None above are correct" can't possibly be the right answer because options one and two are correct. They must be combined for the right answer to this particular question but it doesn't make any of them incorrect, when individually looked at. This calls for a CheckBoxList, not a RadioButton.

But Option 1 and 2 are not correct (The comments in blue below these options explains why they are incorrect). Why do you think they are correct?
