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

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

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

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

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