Read this stanza from “The Raven” by Edgar Allan Poe. But the Raven still beguiling all my fancy into smiling,
Straight I wheeled a cushioned seat in front of bird, and bust and door;
Then, upon the velvet sinking, I betook myself to linking
Fancy unto fancy, thinking what this ominous bird of yore—
What this grim, ungainly, ghastly, gaunt, and ominous bird of yore
Meant in croaking “Nevermore.”

How does the symbol of the raven in these lines reflect the meaning of the poem?

It suggests the sorrow and finality of death.

It shows that death conquers love.

It hints that true love can never really die.

It provides hope that there is an afterlife.
