Hey Ttunden,
On a question like this, it's important to understand the argument as deeply as possible. This is a complex one, so we have to be extra careful.
Conclusion: When Medical Pros are stupid, it's not for the same reason as when regular people are stupid.
Premises: Regular people don't know anything, but medical pros know lots of stuff.
That's the overall argument. Let's take a look at the answers now.
A) This isn't an analogy, because the two groups are DIFFERENT (in an analogy, the two would be the same).
B) There's no hypothesis being argued against here. The author straight up says that there are two different reasons for why normal people and medical pros are susceptible to fraud. Now, if the author had said something like "The reason people fall for fraudulent claims is NOT because they lack medical knowledge, as evidenced by the fact that doctors fall for them, too", then B would be correct. But the author sets forth two separate hypothesis; namely that normal people fall victim because they have no knowledge, and medical pros fall victim for some other reason (it's never stated).
(C) No doubt is cast on their expertise; just look at the last sentence.
(D) This is the answer. "arguing that since two groups are disanalagous in important respects" -- this refers to the regular folks and the medical people, who differ in their knowledge of medical stuff. "there must be different explanations for their similar behavior" -- both of them fall for frauds, so that's the similar behavior, and the "different explanations" is mentioned in the second to last sentence of the passage ("However, the same explanation cannot be given...")
(E) There's no evidence cited against the conclusion itself.
Hope that helps!
