<u>Answer</u>:
B: “And the lovely blue isn't even blue, is it? isn't even there, is it?"
This detail helps illustrate the author's point in "Against Nature".
<u>Explanation</u>:
The story “Joyce Carol Oates” states that nature doesn’t give any instructions for humans. Joyce is not against nature in her story, but she questions about her own existence and she thinks she doesn’t exist.
Oates suffered from cardiac attack and while she is lying down on her back, she goes through a thought process. Her mind roams around and Oates uses imagery to depict what is going on around her. She searches the area around her, talks about the nature.
This line shows that Oates is trying to say that nature has connection with no spiritual truth as she is even questioning the color of the blue sky that whether that is also true or not.
