Which statement best describes the impact of Poe's use of repetition in this poem?

A It makes the poem sound like a song with a repeated refrain.

B The repetition creates a nightmarish sense of inevitability: the speaker (and the reader) knows what is coming but as powerless to avoid it.

C it pushes the reader to pay attention to the words that are not repeated.

D The repetition is only used on important words within the poem; Poe wants to call attention to those words, so he uses them frequently.
