A. Perhaps, one of them is right. Perhaps, both of them are wrong. This was not validated by the stimulus.
B. this is extreme. Them not knowing as much is not validated in the stimulus.
C. I don't feel strongly about this but after eliminating a,b,d and e. this became my response.
D. Cavities not mentioned in the stimulus. The dentist may have other reasons.

I like A better than C. Rest all can be eliminated.
Different health problems or same health problems in C cant be confirmed.
A avoids this debate by pointing things to further research. Also A just points out the disagreement via The dentists and the nutritionists cannot both be right

A for me.

Hmm. But, how about the inference it made about further research... Perhaps, it doesn't have to go this far to know what is the best advice.
It's not mentioned in the stimulus.

I agree about your point in C. Difficult to consider one and leave another.

Hi,

This question uses too much common knowledge (that nutritionists and dentists are concerned about different problems) in an inference problem. This does not look like a typical GMAT problem.

Also, option A cannot be the answer since neither nutritionists nor dentists are claiming their way to be the best way; they are just advising. If they were saying that the best way to eat candy...., then option A could be worth considering. But this is not the case. For example: If someone advises you to solve all OG questions, you cannot say that he is right or wrong. Only when the other person says that solving all OG questions is the only way to score 700 on GMAT, then you can label him right or wrong.

Thanks,
Chiranjeev

From an Inference question perspective, all of these answer choices are wrong. It is impossible to infer them from the information given.

This is not even a GMAC question based on a quick Google search, so it is not worth studying.
