Answer 1

Option (D), The setScene method of JavaFX's Stage class is used to place a Scene onto a Stage, which is crucial for displaying UI elements and graphics in a JavaFX application.

Step-by-step explanation:

The method setScene in JavaFX's Stage class is used to place a Scene onto a Stage. This is fundamental for displaying graphical content in a JavaFX application. The Scene acts as a container for all content in a JavaFX application, and setting it on the Stage is necessary to display the content to the user. This content could include UI elements like buttons, text fields, and graphics. It's important to note that the root node of the Scene graph is where all these elements are attached, and this root node is then set into the Scene which is placed on the Stage.
