The correct answer is D. the tone is intense and tells the reader that the speaker is very mad at the raven.
In the poem, the speaker is talking to the raven, asking him some questions, to which he replies 'Nevermore.' As the poem progresses, the narrator's questions become more and more personal, until he asks the bird if he will ever see his beloved Lenore again, to which the raven obviously replies "Nevermore." This is the moment when the narrator finally snaps, showing his anger and hatred towards the bird and pain for the loss of his love.
