To determine which literary device is used in the poem, you would need to provide the text of the poem or specific lines from it. Each of the options represents a different literary device:
A. Rhyme - The repetition of similar sounds, typically at the end of lines. B. Metaphor - A figure of speech that makes a comparison between two unlike things without using "like" or "as." C. Onomatopoeia - A word that imitates the sound it represents (e.g., buzz, hiss). D. Alliteration - The repetition of the same initial consonant sounds in a series of words.
If you provide the poem or lines from it, I can help identify which literary device is being used.
