Choose the correct definition for <apex:actionFunction>.

• A.Can be associated with an AJAX request (actionFunction/actionSupport/actionPoller) and shows content conditionally depending on the status of the request (in progress/complete). Use the "id" field to specify name; use "status" field on related components to connect them
• B.Signifies which components should be processed by the server when an AJAX request is generated
• C.Adds AJAX support to another component (e.g. onClick, onMouseUp, onFocus, etc.)
• D.Sends an AJAX request according to the time interval you specify. If this ever gets re-rendered, it resets
• E.Allows for controller methods to be called directly from Javascript. Must be encapsulated in
  <apex:form> tags. Unlike actionSupport, these function<apex:actionPoller>s can be called directly from Javascript code
