The answer B somehow gives us the reasoning why he does not trust the person (because he does not trust that person, he will not buy that milk)
However, the answer C says that the tennis ball is a good performer, because it is effective. It is the same way of saying that "i am good at Math, because I always was good at Math". flawed logic.
The correct answer should be C, I think

People post the OA!!

IMHO:C

Dr.A has arrived on his conclusion and he is sticking to it.The evidence presented does'nt deter him.He is not presenting any evidence to his belief.C duplicates this.

In B,the author is giving a reason.BECAUSE he does'nt trust the person he will not buy the milk.>Eliminate

I d say C....If you look carefully at the quetion..It checks the reasoning of A ...He says a statement without the backing of any credible proof or statistical data.

Only C doesnot have a statistical backing.

I've seen this before and remember the answer as C.
reason was that both Dr's analysis and the analysis in C has messed-up cause-affect

The OA is C. C is the only answer with no backing and is only based on an opinion.
