Which literary form commonly has the purpose of explaining scientific phenomena?

C. Expository essays are specifically designed to inform, explain, or describe a topic to the reader. This literary form utilizes clear, straightforward language to convey facts and information, making it particularly effective for exploring scientific phenomena. The aim of an expository essay is to educate the audience about a specific subject, often using evidence, examples, and logical organization to present complex ideas in an understandable manner.

In contrast, other literary forms serve different purposes. Fiction often focuses on storytelling and character development rather than factual explanation. Biographies primarily recount the lives and experiences of individuals, offering personal insights rather than scientific analysis. Poetry, with its emphasis on artistic expression and emotional resonance, typically does not prioritize straightforward explanations of scientific concepts. Therefore, expository essays stand out as the appropriate choice for the purpose of explaining scientific phenomena.
