How does edgar allan poe build suspense in "the raven"?

a. by making the bird say more and more horrific things

b. by repeating the tapping sound at the speaker's door

c. by having the wind blow out the candles in the chamber

d. by worsening the storm as the poem progresses

The correct answer is:  B.  By repeating the tapping sound at the speaker's door. On a sad night the narrator reads a book when he hears a knock on the door of his room, thinks he is just a visitor and that he will attend the next day because his pain over the death of Lenore is very strong, the strident curtains they scare him, then he decides to open the door, he apologizes to the visitor, when he opens the door he does not see anyone and he only hears the echo of the word Lenore, returns to the room and again he hears the pounding, thinks that it could be the wind outside the window, but when he opens the window a raven enters and perches on his door.
