Answer: D. The author refers to the garden of Eden to show that nature's beauty is short-lived.
Explanation: allusion is a literary device that consists in making a brief reference to a person, an event (historical, political, cultural, etc), or a place. In the given excerpt from "Nothing Gold Can Stay" by Robert Frost, we can see that the speaker makes an allusion to a place (the Garden of Eden), this allusion helps to show that nature's beauty is short-lived (like the Eden when it sank to grief).
