People who are allergic to cats are actually allergic to certain proteins found in the animals ' skin secretions and saliva; which particular proteins are responsible, however, varies from allergy sufferer to allergy sufferer. Since all cats shed skin and spread saliva around their environment, there is no such thing as a cat incapable of provoking allergic reactions, although it is common for a given cat to cause an allergic reaction in some - but not all - people who are allergic to cats.

Which one of the following statements is most strongly supported by the information above?

(A) Any particular individual will be allergic to some breeds of cat but not to others.
(B) No cat is capable of causing an allergic reaction in all types of allergy sufferers.
(C) Not all cats are identical with respect to the proteins contained in their skin secretions and saliva.
(D) The allergic reactions of some people who are allergic to cats are more intense than the allergic reactions of other allergy sufferers.
(E) There is no way to predict whether a given cat will produce an allergic reaction in a particular allergy sufferer.

Not sure how C can be the answer-though CDE all look to be contenders. E is a bit extreme but D looks good.

It's between B and C. B is explicitly in the question; the negation of C is impossible since that would mean every cat is capable of causing a reaction in every allergy sufferer.

Fact 1: People are allergic to certain proteins found in cats' skin secretions and saliva (not the cat itself)
Fact 2: Each allergy sufferer is allergic to different proteins.

Premise 1: All cats shed skin and spread saliva around their environment
Premise 2: A given cat could cause allergic reaction in some people

Conclusion: All cats are capable of provoking allergic reactions.

(A) This choice is logically wrong.

"X is linked to some of Y" doesn't mean that "Y is linked to some of X". There could be a certain member of Y is linked to all of X or none of X.

(B) This choice is too extreme. There could be a member of X is linked to all of Y.

(C) Not all cats are identical with respect to the proteins contained in their skin secretions and saliva.
Correct. This choice means that some cats have identical proteins contained in their skin secretions and saliva and some cats have different proteins contained in their skin secretions and saliva.

(D) Comparison between allergic reactions is out of scope.

(E) The argument doesn't mention anything about predicting whether a given cat will produce an allergic reaction in a particular allergy sufferer.
