What is the purpose of the Apple Books app?

The Apple Books app serves as a comprehensive platform for users to read, purchase, and organize digital books and audiobooks. This purpose aligns with the growing demand for digital reading materials and audiobooks in a convenient format that can be accessed on Apple devices. Users can browse a wide selection of titles, add their own books in various formats, and create personalized reading lists and collections. Additionally, the app offers features such as bookmarks, notes, and highlighting, enhancing the reading experience.

While other options such as downloading music and podcasts pertain to different applications, and managing spreadsheets or editing photos relates to productivity and creativity apps, they do not capture the specific functionalities and goals of the Apple Books app. This focused functionality is what distinguishes the Apple Books app and makes option B the correct choice.
