Which of the following most logically completes the argument?

Ferber's syndrome, a viral disease that frequently affects cattle, is transmitted to these animals through infected feed. Even though chickens commercially raised for meat are often fed the type of feed identified as the source of infection in cattle, Ferber's syndrome is only rarely observed in chickens. This fact, however, does not indicate that most chickens are immune to the virus that causes Ferber's syndrome, since _____________.

(A) chickens and cattle are not the only kinds of farm animal that are typically fed the type of feed liable to be contaminated with the virus that causes Ferber's syndrome

(B) Ferber's syndrome has been found in animals that have not been fed the type of feed liable to be contaminated with the virus that can cause the disease

(C) resistance to some infectious organisms such as the virus that causes Ferber's syndrome can be acquired by exposure to a closely related infectious organism

(D) chickens and cattle take more than a year to show symptoms of Ferber's syndrome, and chickens commercially raised for meat, unlike cattle, are generally brought to market during the first year of life

(E) the type of feed liable to be infected with the virus that causes Ferber's syndrome generally constitutes a larger proportion of the diet of commercially raised chickens than of commercially raised cattle

The argument states that potentially infected chicken, which are turned into feed for cattle, do not test positive for Ferber's disease. Yet, the cattle still become infected. What could account for this discrepancy? Well, if the chickens are infected but are asymptomatic (the disease does not outwardly manifest itself), then such occurrence would help explain why cows become infected by chicken feed.

(D) nicely provides an explanation: Ferber's disease takes more than a year to show any outward signs in infected animals. Since most chicken that are turned into chicken feed are less than a year old, the disease never has a chance to manifest.

Hope that helps :)

Given:
Ferber's syndrome is transmitted through infected feed.
Cattle feed is similar to chicken feed.
Though cattle show Ferber's syndrome, it is rarely observed in chickens. Why?

(A) chickens and cattle are not the only kinds of farm animal that are typically fed the type of feed liable to be contaminated with the virus that causes Ferber's syndrome - Other farm animals - Out of scope - Incorrect
(B) Ferber's syndrome has been found in animals that have not been fed the type of feed liable to be contaminated with the virus that can cause the disease - Passage talks about infected feed - Out of scope - Incorrect
(C) resistance to some infectious organisms such as the virus that causes Ferber's syndrome can be acquired by exposure to a closely related infectious organism - Information not provided in the passage. Cause of infection is due to infected feed but not infected animals - Incorrect
(D) chickens and cattle take more than a year to show symptoms of Ferber's syndrome, and chickens commercially raised for meat, unlike cattle, are generally brought to market during the first year of life - Chicken are killed within one of its life but cattle are brought to market much later. Ferber's syndrome can be observed only a year after the infection - Correct
(E) the type of feed liable to be infected with the virus that causes Ferber's syndrome generally constitutes a larger proportion of the diet of commercially raised chickens than of commercially raised cattle - It is mentioned in the passage that cattle and chicken are fed with similar feed - Incorrect

Could you help me to analyze and point out the gap of this argument ? Thanks!

Ferber’s Syndrome
 
Step 1: Identify the Question

This is a fill in the blank question. The word since just before the blank indicates the need for another premise to support the conclusion, so this is a Strengthen the Argument question.
 
Step 2: Deconstruct the Argument

Feed → FS in cattle
Same feed → but FS rare in chick
© Chick not immune b/c ____.
 
Step 3: Pause and State the Goal

On Strengthen questions, the goal is to find a piece of information that would make the conclusion more likely. Besides immunity, what other reason could there be that Ferber’s syndrome is NOT found frequently in chickens?
 
Step 4: Work from Wrong to Right

(A) The conclusion relates to the immunity of chickens. Whether other animals eat the same feed is not relevant.
(B) This answer suggests that there may be other causes of Farber’s Syndrome; it does not help explain why chickens do not often get Farber’s syndrome from feed.
(C) This information could help explain how chickens acquire immunity to Farber’s syndrome. But the conclusion, which the correct answer should support, states that chickens are not immune to Farber’s syndrome.
(D) CORRECT. This answer provides information about why symptoms of Ferber’s syndrome would not be observed in chickens even though the chickens are not immune; the chickens do not live long enough to show symptoms.
(E) If the food is a more important component of the chickens’ diet than the cows’ diet, it seems more likely that the chickens would acquire Ferber’s syndrome if they lack immunity. This answer actually weakens the argument.
