Hi!

allergic
/�ˈl�rjik/ adj. caused by or relating to an allergy: an allergic reaction. ▪ having an allergy to (a substance): allergic to the sting of bees. ▪ (allergic to) inf. having a strong dislike for: I'm allergic to the hype.

Conclusion:

Allergic to---is the correct idiom.

It is just testing the idiom "allergic to"

Answer MUST be C.

I don't really understand why the GMAT tests such things. Either you are native speaker or not. Questions like these are really disappointing.

good question. What is the source of this question.

Somehow, I don't agree with the explanation given above : Idiom "allergy to"

Here is what I found :

Researchers have questioned the use of costly and experimental diagnostic tests to identify food allergies,
such as to <identify> milk, that supposedly disrupt normal behavior.

milk is given as an example of food .
So 'to' is necessary.

If it is not an OG problem, then I would not like to remember it.
'such as to' : was very awkward for me also.
