The correct answer is a short story.
Your options are tragedy, short story, lyric poem, and expository essay. The answer cannot be tragedy because tragedy relies of dialogues and emotions rather than narration. It cannot be a lyric poem because it is solely about emotions. An expository essay is just telling you how to do something - or how something is achieved.
We are left with a short story - it uses narration to tell us what is going on and it describes people and their experiences.
