Question

How does poe use a sound device in this excerpt

Answer 1

The answer is B: He uses alliteration to link images of the sea with images of death.

Answer 2

Had to look for the missing details and here is my answer.

Here is the excerpt:
In her sepulchre there by the sea—
In her tomb by the sounding sea.

This is actually taken from the poem "Annabel Lee" which was written by Edgar Allan Poe.
So in this excerpt, the sound device he used here is ALLITERATION. His purpose here is to connect the image of the sea with death.
Hope this answer helps.
