The correct answer is C. metaphor.
"Bright beams" that Nature has wrapped in black are Stella's eyes. In a way, it is also a simile, but every metaphor is a contracted simile (without "like").
There are other literary devices in this passage as well: contrast (black - bright), rhetorical question (one that doesn't have an answer, or an answer is obvious)...
The answer is the figurative language describes the violence of the scene. The poem used figurative language in order to give emphasis on important details that makes it sound like poetic. Figurative language are used in order to symbolize or give meaning to an idea in a not so obvious way.
