OK, I answered C because A and B are so completely wrong that C is the only option where we can reasonably guess that the setter of the question got it wrong enough to think C would work. So I got my point - for understanding the sort of stupid error that the question setter would make, not for producing a correct answer (because "(D) none o the above" is the correct answer, but not available). This is a really bloody awful question and answer.

I'm seeing far too much of thios sort or thing in QOD. Presumably it's completely unmoderated?
