The speaker is saying that no matter how much power, beauty or wealth someone has, everyone dies in the end, death is inevitable so all the things someone acquires in life don't really mean anything. Therefore the correct answer would be option A: "Fame and fortune are ultimately meaningless, because we all die". Option B is incorrect because the author never mentions cities or the country. Option C is incorrect because the author doesn't convey that idea, he just says that everyone dies, and option D is incorrect because the author does not mention literature.
