Answer:
The correct answer is The raven, who represents the speaker's mourning, arrives and never leaves.
Step-by-step explanation:
In The Raven Poem, what the raven represents are the thoughts that the speaker is not ready to face, but somehow knows that they are there tormenting him, and once he notices them, they will never leave.
His grief comes from having lost his only one true love, and he is tormented to know that he will never see her again or find someone like her.
And that is what the crow represents. Every question that the speaker asks and to which he only gets the answer “Nevermore” is also part of his conscience, understanding that he will never see his beloved again, and will never find a woman the same.
Therefore, the most appropriate answer is The raven, who represents the speaker's mourning, arrives and never leaves.
