Answer:
A. "Things might have gone on very happily indeed, and the Golden Age might really have come again, had it not been for Jupiter." (paragraph 17)
Step-by-step explanation:
In James Baldwin's "The Story of Prometheus and Pandora's Box," the narrator relates how Prometheus stole fire from Jupiter for the humans and thus brings the curse upon all mankind. This myth reveals how Pandora opened the box given by the gods and thus brought all forms of disaster to the whole human race.
And while describing the story, the narrator also talks about how Jupiter was responsible for all of the misery upon mankind. Prometheus may have stolen the fire after he refused to give it to him, but it was the punishment for that betrayal that led to the suffering of the whole human race. So, the quote from the text that reveals the narrator's perspective about how Jupiter is responsible for mankind's misery is option A. The fact that he claims "things might have gone on very happily indeed . . . had it not been for Jupiter" shows he blames the god for everything.
