Which of the following best describes expository writing?

Expository writing is characterized by its primary goal of informing, explaining, or educating the reader about a specific topic. It presents facts, ideas, or processes in a clear and logical manner without the author's personal opinions or emotional influence. This type of writing often includes definitions, explanations of concepts, comparisons, and factual evidence, allowing readers to gain a deeper understanding of the subject matter.

In contrast, storytelling is a hallmark of narrative writing, which focuses on creating a fictional tale or recounting events, while emotional expression is typically found in expressive writing. Lastly, narrative structure is a feature of storytelling, where elements such as plot, characters, and setting come into play. Therefore, the best description of expository writing is one that emphasizes its informative and explanatory purpose.
