Which tab is only active when a user has saved a book?

• A. Designer tab
• B. Report tab
• C. Preview tab
• D. Book tab

Answer: (C)

The main idea is that the Preview tab is tied to a stored, finalized object. Preview shows you how the book will look when it’s saved, using the actual saved data and layout. Because a preview requires a concrete, saved book to render, the tab becomes active only after you’ve saved. Until then, you’re working with draft content, and there’s nothing saved to preview. The other tabs serve different roles: Designer is where you assemble and configure the book’s pages, Report lets you view report-related content, and Book provides access to the collection of saved books. These can be used in the editing or navigation stages, but previewing depends on having a saved book to show.
