What allows users to select a directory in the application?

Label
DirectoryDialog
Button
Slider

The correct answer is: DirectoryDialog

A Label is a simple widget used to display one or more lines of text. It does not have the functionality to allow users to select a directory. A Button is used to trigger an action, such as submitting a form or navigating to another page. It also does not have the ability to select a directory. A Slider is a widget used to set a value within a specific range. It does not have the functionality to allow users to select a directory. A DirectoryDialog is specifically designed to allow users to browse and select a directory in an application. It opens a dialog box that displays the file system and allows the user to navigate to the desired directory. This makes it the correct choice for allowing users to select a directory in the application.
