The correct answer is B. A life that is nearing its end and a fading sunset
Step-by-step explanation:
In this passage from "Sonnet 73" by Shakespeare the author refers to the inevitable death. Moreover, to explain this idea the author compares it to the sunset and night. This can be seen in "As after sunset fadeth in the west... by black night doth take away" which shows the "black night" is preceded by the end of the sunset. Moreover, in the line "death's second self, that seals up all in rest" the author shows similar to the end of the sunset, life is ending, and when night falls everything would end. Thus, the things compared are "a life that is nearing its end and a fading sunset."
