The answer is the B: The Navigation Pane
All the objects in a Microsoft Access database are listed in the Navigation Pane. You can view and manage the categories and groups of objects in the Navigation Pane. You can also hide groups, objects, or the entire Navigation Pane. In addition, you can also use the Navigation pane to sort objects, find objects in a database, and add objects to a custom group. By default, the navigation pane appears when you open a database in Access.
