Consider the following code snippet:
Final RectangleComponent component = new RectangleComponent();
MouseListener listener = new MousePressListener();
Component.addMouseListener(listener);
______________
Mystery.add(component);
Mystery.setSize(FRAME_WIDTH, FRAME_HEIGHT);
Mystery.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Mystery.setVisible(true);
Which of the following statements completes this code?
A) JPanel mystery = new JPanel();
B) JComponent mystery = new JComponent();
C) Frame mystery = new Frame();
D) JFrame mystery = new JFrame();

Question

The code indicates the creation of a JFrame with the following properties: 
- It will contain a RectangleComponent that was created earlier.
- An instance of a MousePressListener is added as a MouseListener to the RectangleComponent.
- The Mystery JFrame will have a size of FRAME_WIDTH by FRAME_HEIGHT.
- The JFrame will close when the close button is clicked.

Therefore, the best choice for the completion of this code would be option D (JFrame mystery = new JFrame();). This is because JFrame is a subclass of Frame and JComponent, and JPanel alone do not have all the necessary properties needed to fulfill the requirements of the code.
