The first line of the second stanza of Robert Lowell's poem, "For the Union Dead," reads: "Once my nose crawled like a snail on the glass." This is an example of

A-simile to suggest the speaker's excitement at seeing the fish

B-conceit to set the tone of sadness throughout the rest of the poem

C-hyperbole to express the intensity of the speaker's memory

D-metaphor to compare the window to a slowly moving snail

Thank you to anyone who can help!!
