The correct answer is D. Marriage restricts one's freedom. This is because of the fact that even though her husband was not a bad man who beat her up or something similar, she was still kind of happy when she heard he died, because she would get to live her life as a free woman, instead of a housewife. This is why it was considered to be a controversial story when it came out.
The word "wonderful" in reference to the "eyes" of the sky indicates that she feels loved and protected. So, the answer is D.
