Final Answer :
D
Explanation :
The validate() method is used to re-layout container components that have been added or removed from the container. This method would therefore update components on the screen. The other methods listed, setVisible() and setLayout(), do not necessarily update components on the screen. The update() method is used to repaint a component, but does not involve layout changes.
