Hi mkarimi73!
Happy to address answer choice (C).
To begin, we're asked whether the authors of the passage would disagree with one another. For this type of question, it can be helpful to put an "A" and "B" next to contender answers. Then, ask how the author of each of the passages would respond to the question. If it's yes/yes or no/no, then this wouldn't be a point of disagreement. In addition, watch out for instances in which it might be possible to supply an answer for one of the passages but not the other; if you don't know how one passage would respond, then this couldn't be the correct answer if asked for a point of agreement/disagreement.
Answer choice (C) states, "People should be imprisoned for actions from which they are not free to refrain." We can make a notation at the outset:
A: ?
B: ?
Next, would the author of passage A agree with this statement? The statement is effectively saying that "people should be imprisoned for actions even if they don't have free will over those actions." In the end, we don't know exactly whether or not the author of passage A would agree with this. The passage does call for getting rid of the notion of blameworthiness, as well as more anticipating how people who break the law will act in the future, but the passage doesn't advocate for or against imprisonment. As such, we're left with a ? for passage A, which is reason enough that answer choice (C) cannot be correct, since we can't verify if this is a point of disagreement.
We could still look at passage B. Doing so, it's additionally unclear whether the author of passage B would agree or disagree. The author notes that some of the purposes of punishment haven't worked, but also that blaming serves important social functions. More to the point, though, the passage doesn't make any overall judgments or advocacy for or against imprisonment. Thus we're left with a ? for passage B as well.
Answer choice (C) is incorrect because we can't verify whether the author of either passage would agree/disagree with the statement. Without this verification, it can't be a point of disagreement between them.
