Which of the following best describes a trade book?

A trade book is best described as a narrative book that tells a story. This type of book is typically published for the general public and can encompass a wide range of genres, including fiction, non-fiction, and biographies. Trade books are generally those that are sold in bookstores and aimed at readers looking for entertainment or information outside of an academic context.

In contrast, the other options represent different types of books that serve more specific purposes. An educational book primarily focuses on teaching or academic content, while a textbook is specifically designed for use in educational settings, providing structured content aligned with a curriculum. A manual for teachers often contains guidelines, strategies, and content focused on instructional methods, which is distinct from the storytelling aspect of trade books. Thus, trade books emphasize narrative and engagement, setting them apart from the other categories listed.
