{The Raven by Edgar Allan Poe] Why does the speaker react poorly to the raven's response of “Nevermore” in stanzas 15-16?

A The speaker is unsettled by the raven’s repetition of “Nevermore” because he believes the raven learned it from a depressed former master and intends to make him his new owner.

B The speaker begs the raven to leave, to which the raven responds “Nevermore”; the speaker becomes frustrated in these stanzas as he attempts to make it leave.

C In these stanzas, the speaker asks the raven if there is an afterlife and if he will be reunited with Lenore there, to which the raven answers “Nevermore”; the speaker takes these answers seriously and thus becomes upset.

D The speaker is frustrated by the bird’s catchphrase and begs it to stop talking.
