The inference that is most strongly supported by the passage is:
C. The raven is a reflection of the narrator’s grief for his beloved.
The line from the text that best supports this answer is:
D. “But whose velvet violet lining with the lamp-light gloating o’er / She shall press, ah, nevermore!”
This line suggests a deep sense of longing and loss associated with the narrator's feelings about someone he has lost, which connects to the raven as a physical manifestation of his grief.
