Here is my logic again: Statement 2 can't give ONLY NO in this case, because, then, both statement will contradict each other. So, if we are 100% sure that there is no NO value in statement 2 (specifically in this example), then we must not try for finding YES value in statement 2 !!! It'll be just waste of time finding YES value in statement 2. Without finding YES, I can definitely say: it is D (Correct option). Am I right?

Responding to a PM:
Yes, I agree that if one statement gives me a definite YES, I will ONLY look for a NO from the other to get a may be. The other statement cannot give me a definite NO.
I do understand that GMAC reps don't necessarily take a definitive stand on this but what I think is that they might be playing the "don't say anything that you could be proven wrong on" game. Since some experimental questions that do not make the cut go into the OG, GMAC reps seems to be ensuring that something like that doesn't catch them unaware.
If contradictory information were possible on two statements, option (C) would make no sense (say the two stmnts are n = 1 and n = 0) and options (A), (B) and (D) would be questionable too (so what if n = 1, apparently it could be something else too such as 0 or for that matter 100 too so stmnt 1 is not sufficient).
Hence, there is no way a valid, scored GMAT question would offer contradictory data, in my opinion.
If option (C) exists, I should be able to consider it - whether I need to or not is beside the point.
For me, every question has to be a complete logical whole. Seeing that GMAT spends a lot of time and money on every question, I am sure that that is what they want too. Also, since GMAT's scoring and item-validating algorithms are extremely data driven, I would be surprised if they let unexplainable data go through (since options (A), (B) and (D) may be chosen randomly)
