B) the compiler will automatically deal locate the memory pointed to by p.
C) the program will suffer from memory leaks.
D) the returning function will throw the bad_alloc exception.

``` import javafx.application.Application; import javafx.scene.Scene; import javafx.stage.Stage; import javafx.scene.layout.HBox; import javafx.scene.shape.Circle; public class Test extends Application { @Override // Override the start method in the Application class public void start(Stage primaryStage) { HBox pane = new HBox(5); Circle circle = new Circle(50, 200, 200); pane.getChildren().addAll(circle); circle.setCenterX(100); circle.setCenterY(100); circle.setRadius(50); pane.getChildren().addAll(circle); // Create a scene and place it in the stage Scene scene = new Scene(pane); primaryStage.setTitle("Test"); // Set the stage title primaryStage.setScene(scene); // Place the scene in the stage primaryStage.show(); // Display the stage } /** * The main method is only needed for the IDE with limited * JavaFX support. Not needed for running from the command line. */ public static void main(String[] args) { launch(args); } } ``` a. The program has a compile error since the circle is added to a pane twice. b.
