Ionce saw a quiet man, staring at the sea. his skin was like the oak bark; his back looked like a c. i felt the wisdom of his eyes seeping into me. i thought he had existed since time could ever be. which literary device does the author use in this poem? a. metaphor b. alliteration c. rhyme d. onomatopoeia

The obvious answer would be C. rhyme.
As you can see, each of these lines rhyme: sea rhymes with C, and me, and be. Those words sound similar, which means they rhyme. There are no metaphors (comparisons) and onomatopoeias (mimicking the sounds from nature) here, or alliterations (repetition of the same consonant) in this excerpt.
