The passage itself doesn't have a conclusion, but we are trying to select an answer choice that would
help us determine whether the capsaicin-laced feed would be useful in raising salmonella-free chicken for retail sale. So we need to select an answer choice that represents information that would help us make that determination. Before we do that, make sure you read the passage carefully and pay close attention to the author's word choice:
- "Meat from chickens contaminated with salmonella bacteria can cause serious food poisoning." - The meat from contaminated chickens CAN cause serious food poisoning, but it doesn't ALWAYS cause serious food poisoning.
- "Capsaicin, the chemical that gives chili peppers their hot flavor, has antibacterial properties. Chickens do not have taste receptors for capsaicin and will readily eat feed laced with capsaicin." - This tells us that capsaicin MIGHT help fight salmonella bacteria (since it has antibacterial properties). Chickens will readily consume capsaicin. So it would not be hard to get chickens to consume a substance that MIGHT help fight salmonella.
- "When chickens were fed such feed and then exposed to salmonella bacteria, relatively few of them became contaminated with salmonella." - Great, so when chickens are fed capsaicin and THEN exposed to salmonella (AFTER ingesting the capsaicin), few of them contracted salmonella. Note that this does not necessary mean that capsaicin will fight salmonella that the chicken already has.

Whether feeding capsaicin to chickens affects the taste of their meat
We are trying to decide whether feeding capsaicin to chickens would help us raise salmonella-free chicken
for retail sale. What if meat from chickens that consume capsaicin tastes awful (or just very different than normal chicken meat)? Sure, the meat would be salmonella-free, but if it tastes weird, consumers might not purchase the chicken. In that case, feeding capsaicin to chickens would not be a useful solution for raising chickens for retail sale. But if the chicken meat tastes the same with or without the capsaicin, then this could be an effective solution. Determining whether feeding capsaicin to chickens affects the taste of their meat would be useful in making the decision, so keep (A).

In evaluate questions such as this one one must get different answer if the answers are yes or no. In answer No to this question, it is readily observed that it will not affect the retail sale.
But here in this question we have two options even in Yes.
You are right in stating that if taste of meat deteriorates it will affect the retail.
However, what if taste becomes better, that is also a change in taste and that is a Positive change. And may be equal number or more people buy it. Then what.
How can we assume that Yes means worse taste. Kindly explain
The question asks us which option would be "most helpful" in determining whether to use the new feed. That's different than asking for something that
proves whether farmers should use the feed. So, we aren't necessarily looking for something that would 100% determine the course of action -- it's enough to find an answer choice that is more helpful than the other ones.
With that in mind, I'll steal from our previous post on this:
Imagine that you are a chicken farmer who raises chicken for retail sale, as specified in the question. Someone tells you that if you lace chicken feed with capsaicin, the chickens will be less likely to become contaminated with salmonella. Sounds great, right?
But wait... capsaicin is the thing that gives chili peppers their hot flavor. Wouldn't you worry about whether this chemical will impact the taste of the chicken that you're trying to sell?
Sure, there's no guarantee that people would dislike the chicken, even if it tasted different. But before you start feeding all of your chickens capsaicin, it would be helpful to know whether the flavor of the product will change, so you can anticipate how it would impact your sales.
While knowing the answer to (A) might not completely change your mind, it would certainly weigh into your decision about whether to feed your chickens capsaicin. So, (A) is still a helpful question to answer.
(A) is the correct answer choice. Mmm... spicy chicken.

I hope that helps!
