I agree. "I don't know" needs to be accepted as a correct choice if offered.

I guess I'm late to the party. I don't see an "I don't know" answer. If I had I would have selected that answer as it would have been right. But apparently I would have been wrong. But that would mean I did know. So I wouldn't have selected it. Oh it's so confusing...
