Which of the following best describes nonfiction?

The best description of nonfiction is writing based on factual information. Nonfiction encompasses a wide range of writing styles and genres, including biographies, essays, journalistic pieces, and instructional texts, all of which provide facts and real events rather than imaginary scenarios or characters. Nonfiction aims to inform, educate, or convey information about the world and real-life experiences, making it distinctly different from fictional narratives or explorations of philosophical beliefs.

Other options involve elements that are characteristic of fiction or subjective interpretation, which do not align with the factual nature of nonfiction. Thus, the emphasis on factual information sets nonfiction apart as a genre dedicated to presenting truths and insights based on reality.
