Thanks for the question! Take a look at the second paragraph, where the author tells us that some cooperating witnesses may fabricate evidence and lie. Then, in the last sentence of the passage, we’re told that jurors might presuppose that accomplice witnesses and jailhouse informants give testimony because they’re atoning as opposed to other external factors, making it more likely that the jurors believe these members. Thus, in some cases, when these people lie and get sentence reductions (which is one of the offers prosecutors make, as evidenced in the second paragraph), then those sentence reductions are unwarranted because they lied. Thus, it can be inferred from the passage that the author would agree with (E). Hope this helps! Feel free to ask any other questions that you might have.
