5. PreferencePortlet is Portlet Specification 2.0-compliant and the system is running IBM WebSphere Portal 8.0. What is the output of the following code? public PreferencePortlet extends GenericPortlet{ protected void processAction(ActionRequest actionRequest, ActionResponse){ actionRequest.getPreferences().setValue("test","ViewModePreferenceValue"); actionRequest.getPreferences().store(); } protected void doView(RenderRequest renderRequest, RenderResponse renderResponse) throws PortletException, IOException { // Generate action URL }

A) This code results in a compiler error because PortletPreference does not have the store() method.
B) The container throws javax.portlet.ReadOnlyException because it is only allowed to view preferences in the processAction() method.
C) The container throws java.lang.IllegalStateException because it is not allowed to change preferences in the processAction() method.
D) The code compiles and executes fine. It stores a "test" preference at the end of the processAction() method call.
