Which of the following best describes a science book?

A science book is best described as a work of nonfiction written by experts. This type of book provides factual information based on research, experiments, and scientific theories, aiming to educate readers about various topics in the field of science. The authors are typically knowledgeable in their respective areas, ensuring that the content is accurate and reliable.

In contrast, a work of fiction may involve invented stories and characters rather than presenting factual information. A collection of poems focuses on artistic expression and emotions rather than scientific concepts. A narrative story, while it can convey a message or theme, is often rooted in fiction and storytelling rather than in factual data or expert analysis. Therefore, the description that highlights the nonfiction aspect and expert authorship accurately reflects the nature of a science book.
