To enhance the availability of an application running under HACMP， a decision was made to use  The application monitoring facility. The application consists of several components and can take several minutes to initialize. The components use socket communication and can be initialized in any order as long as it is a serial order. The customer’s concern is that if the application stop and start scripts are used during application monitoring recovery，it may take an extraordinary length of time to reset all of the application components.  What can be done to ensure the best recover time？（）   

• A、 Use a process monitor that restarts the named processes in the original start order.
• B、 Use the defined application start and stop scripts to control the application if there is a failure.
• C、 Use multiple application monitors for this resource group to enable the monitoring of the specific components of the resource group.
• D、 Use application cleanup and restart scripts designed to determine the state of the various components of the application and start only the parts required.
