What type of writing describes imaginary characters and events?

Fiction is the correct answer because it specifically encompasses narratives that are created from the imagination rather than being strictly tied to real events or facts. This category of writing allows for the exploration of imaginary characters, settings, and events, which can range from fantasy and science fiction to more realistic scenarios. Unlike nonfiction, which focuses on factual recounting and real-life experiences, fiction presents a world shaped by the author's creativity.

Biographies and autobiographies, while they tell stories, prioritize real people and actual experiences, making them distinct from fiction. Thus, fiction stands out as the genre dedicated to the art of storytelling through invented characters and scenarios.
