None

12.

What is a common use case for using the popUpTo() method with the inclusive option?

None

13.

How can you pass arguments between destinations in Compose navigation?

By passing the argument directly in the destination composable function.

By creating a new NavHost instance for each destination.

By using a Bundle object only.

None

14.

How do you ensure that back navigation returns to the start destination when using BottomNavigation?

By disabling the back button functionality.

By using the popUpTo() method with the findStartDestination() option.

By setting the navController to always start at the home route.

By creating a new instance of the NavHostController for each navigation.

None

15.

Which of the following best describes the NavHost?

A UI component that manages multiple background services.
