Which of the following most logically completes the argument below?

Using antibiotics to kill Toxoplasma, a parasite that attacks animals with a weak immune system, presents a difficulty: how to keep the immune system from being damaged along with the parasite. For at least some species of animals, a special medicine that prevents antibiotic-based damage of the immune system, is being developed. This protection wears off as the animal matures. Therefore, the special medicine will be especially useful for Toxoplasma-vulnerable animals that _____________ .
(A) carry their newborn babies inside of them over an extended period of time, as elephants do
(B) produce chemicals simulating the effect of the special medicine after several treatments
(C) produce, as they develop beyond puberty, immune cells strong enough to keep Toxoplasma from surviving
(D) are raised in large-scale indoor confinement operations, as chickens are
(E) are kept outdoors inhabiting free-ranging environments

C seems best here: produce, as they develop beyond puberty, immune cells strong enough to keep Toxoplasma from surviving

reasoning: the argument is talking about some antibiotic that can kill some weird parasite called T. however there might be some "antibiotic based damage as well" .So a special medicine is being made to prevent this "antibiotic based damage" . the protection of this "new antibiotic" will wear off as animal matures. now we have to realize that such an "antibiotic" will only be useful to an animal who can develop cells immune to that "parasite" because once the effect of that "new antibiotic" wears off then that animal will be self sufficient to fight the parasite !!

I'm thinking B here--I was also between B and C.

I think because C mentions puberty, it seems out of scope? Also, we don't know how long it is until the animal reaches puberty. So, I believe that B is a better answer as it only takes a few treatments to stimulate production of cells/chemicals that simulate the effects of the special medicine.

(A) carry their newborn babies inside of them over an extended period of time, as elephants do - irrelevant
(B) produce chemicals simulating the effect of the special medicine after several treatments - this exacerbates the problem
(C) produce, as they develop beyond puberty, immune cells strong enough to keep Toxoplasma from surviving - correct, immune system is stronger when the effect of Toxoplasma is higher
(D) are raised in large-scale indoor confinement operations, as chickens are - not a strong enough reason
(E) are kept outdoors inhabiting free-ranging environments - opposite

Can you provide OA?

I believe that the answer here is C.

The animals that are most sensitive and likely to be damaged from Toxoplasma will be given the antibiotic which protects them as they mature. The antibiotic effectively gives them cover until their own bodies produce immune cells that protect them.

"Therefore, the special medicine will be especially useful for Toxoplasma-vulnerable animals that _____________ ."

The medicine is useful for "Toxoplasma-vulnerable animals" until they are no longer "Toxoplasma-vulnerable".

For at least some species of animals, a special medicine that prevents antibiotic-based damage of the immune system, is being developed. This protection wears off/ becomes less effective as the animal matures.

Before maturity the animals should develop immunity to protect themselves.

Clear C.

(A) carry their newborn babies inside of them over an extended period of time, as elephants do
(B) produce chemicals simulating the effect of the special medicine after several treatments
(C) produce, as they develop beyond puberty, immune cells strong enough to keep Toxoplasma from surviving
(D) are raised in large-scale indoor confinement operations, as chickens are
(E) are kept outdoors inhabiting free-ranging environments
