You are developing an application that receives events asynchronously.You create a WqlEventQuery instance to specify the events and event conditions to which the application must respond.You also create a ManagementEventWatcher instance to subscribe to events matching the query.You need to identify the other actions you must perform before the application can receive events asynchronously.Which two actions should you perform？（）

• A、Start listening for events by calling the Start method of the ManagementEventWatcher.
• B、Set up a listener for events by using the EventArrived event of the ManagementEventWatcher.
• C、Use the WaitForNextEvent method of the ManagementEventWatcher to wait for the events.
• D、Create an event handler class that has a method that receives an ObjectReadyEventArgs parameter.
• E、Set up a listener for events by using the Stopped event of the ManagementEventWatcher.
