The answer is D: Yu Tsun.
This short story, by Argentinian writer, Jorge Luis Borges, is told from the point of view of Yu Tsun, a Chinese professor who signs the statement that we, as readers, confront as the story.
The story itself is highly complex, but, according to some, like philosopher Gilles Deleuze, it was inspired on Leibniz´ notion of “composible worlds”, only that the Argentinian believes that there is not only one possible and best universe, rather, there are several, all at once.
