Answer: C. Parallelism.
Explanation: in poetry and literature, parallelism is a literary device that consists in the repetition of words, phrases or grammatical structures, in order to make the text more symmetric, add rhythm or make it more effective. In the given excerpt from the Sonnet 9 by Edmund Spenser, we can see a clear example of parallelism, when the author uses the same structure in the phrases "...not to the sun: for they do shine by night", "..not to the moon: for they are changed never," etc.
