The correct answer is 2, which refers to Thomas Mann. The story in question is “Death in Venice” (originally “Der Tod in Venedig”), a novella by Mann that explores themes of obsession, beauty, and decay. The protagonist, Gustav von Aschenbach, is a writer who becomes infatuated with a young boy named Tadzio during his stay in Venice, which leads him to confront his own mortality and artistic disintegration. The themes of obsession, death, and aesthetic decay are central to Mann’s narrative, making him the correct author for this story.
