Suppose the question asks whether the number m is odd?

Question

Hi.. I have small confusion related to Data Sufficiency problem answering?

Suppose the question asks  whether the number  m  is odd?

If statement 1 proves it is even & statement 2 proves it is odd, both individually are able to answer the question in either Yes or No.

So what will be the answer choice..

Is it option D because both of them are sufficient to answer the question?
OR
Is it option B, because statement 1 proves it to be even so Insufficient & statement 2 proves it to be Odd & sufficient?

This query is bugging me a lot... Not clear if a statement can be sufficient even if it answers in negative.

Technically answer would be D, as  EACH statement ALONE is sufficient to answer the question .

But even though formal answer to the question is D (EACH statement ALONE is sufficient), this is not a realistic GMAT question, as:  on the GMAT, two data sufficiency statements always provide TRUE information and these statements never contradict each other .

So we can not have answer  NO  m  is not odd  from statement (1) and answer  YES  m  is odd  from statement (2), as in this case statements would contradict each other.

You won't see such a question on actual GMAT.

Hope it helps.
