Answer: (b).A so-called event is generated and other components express their interest in the event. Explanation:In the implicit invocation style, a component is not invoked explicitly, instead, a so-called event is generated, and other components may express their interest in this event by associating a method with it, which is automatically invoked each time the event is raised.
