B is the best anwser for this question
The answer is B. "Frightened."
You can draw the conclusion that the author is trying to communicate a frightened tone by the diction of the stanza. The following line of the text states: "In the silence of the night, How we shiver with affright..." This is a very telling detail that supports the idea that the author's tone was meant to be frightening.
