Which statement is true regarding the navigation graph file in a note-taking app?

In a navigation graph file for a note-taking app, it's important to understand the structural relationships between fragments (or screens) and how they navigate. The correct statement encompasses multiple truths about the navigation structure.

When considering the statement that both the books list and notes list are destinations, this is aligned with how navigation graphs function. Destinations are typically different parts or screens of the application, such as a fragment representing a list of books or a list of notes. Each can be thought of as a unique destination the user can navigate to within the app.

Furthermore, the presence of an action defined for navigation from the books list to the notes list is crucial. Actions establish pathways between destinations in the navigation graph, enabling transitions when users interact with the app (for example, tapping a book to see its related notes).

When both of these components (the destinations and the defined action) are true, it underscores the interconnectedness of the app’s structure, allowing users to naturally navigate through different parts of the app. This makes understanding and implementing navigation graphs in Android applications more effective, as they define user journeys through an app’s UI.

Thus, the statement asserting that only options A and C are true correctly summarizes the functionality and relationships within the navigation graph file for the
