What type of essay primarily focuses on explaining information?

The correct answer is C, as an expository essay is designed specifically to explain, inform, or describe a particular subject or topic. This type of essay presents facts, analyses, and explanations without the author's personal opinions or emotions influencing the narrative. The goal of an expository essay is to provide clarity on the subject matter and to communicate information in a clear and straightforward manner, often utilizing evidence, statistics, and examples to support the information presented.

In contrast, a persuasive essay aims to convince the reader of a particular viewpoint or argument, often relying on emotional appeal and personal opinions. A descriptive essay focuses on painting a picture with words, emphasizing sensory details to create vivid imagery rather than explaining information. A narrative essay tells a story and typically involves characters, a plot, and a setting, prioritizing a sequence of events over straightforward information dissemination.
