The correct answer is B. Like a lyre with strings that always make new sounds, humans respond uniquely to different experiences.
Step-by-step explanation:
A comparison occurs when two elements, ideas, objects or entities share a common trait or features, which is used in literature including poems to create complex ideas. In the case of the text presented which is poem "Mutability" by Percy Byshee Shelley, the author explores human nature and the way this changes, because of this, in the stanza presented the author states lyres produce different sounds depending on wind or movement "Give various response to each varying blast" and similarly humans respond differently depending on the situation or experiences they have which is stated as the author uses "or like" to stablish a link between lyres and humans. Therefore, the idea conveyed is that "like a lyre with strings that always make new sounds, humans respond uniquely to different experiences".
