The correct answer is "Everything That Rises Must Converge" because it is a collection of short stories written by Flannery O'Connor, who is known for her profound and often unsettling explorations of morality, spirituality, and the human condition in the Southern Gothic style. This particular work, published in 1965, includes themes of social change and complex character interactions, which are hallmarks of O'Connor's literary style.

"1984" is a dystopian novel authored by George Orwell, exploring themes of totalitarianism and surveillance.
