Answer: I would contend that the right answer is the B) The short story describes the mental state of each character better than the play.
Explanation: Just to elaborate a little on the answer, it can be added that options A and C can be easily discarded, since it is the short story, "A Jury of Her Peers," and not the play, the one that provides more detail and explanations, judging at least from these excerpts. Since the play does not provide any information about the characters, it is not possible to know if they have different views than their counterparts in the short story, so option D can also be discarded. Option B is, therefore, the correct option, since the short story does describe the mental state of the characters—the county attorney and Mrs. and Mr. Hale—in more detail, helping the reader to better understand them. It describes, for instance, how the attorney posed the question ("in a way of letting what was past and gone go") and Mrs. Hale's concern about the way her husband would reply to it.
