I would say b and c, since unfasten and clench are basically antonyms and those answers both have antonyms
The answer is: The personification makes the setting more vivid to the reader.
Figurative language is a nonliteral, metaphorical or symbolic choice of words, and personification occurs when something nonhuman possesses human qualities, or when an abstract attribute takes human shape.
In the passage from "Morte d'Arthur," by Alfred Lord Tennyson, personification is used to offer readers a more forceful or powerful description of the scene. For example, <em>mighty bones, the wind-sea sang shrill</em> and <em>flakes of foam.</em>
In that part of the story where Phoenix encountered the hunter, Phoenix told the hunter to use his dog to get rid of the other dog, but after a while the hunter returned and turns out he just scared the other dog. Also while he was pointing a gun at Phoenix, he believed what Phoenix said about her having a lot of experiences about that situation, so the hunter showed respect by not doing it.
