Which of the following statemets regarding Control Plane Policing （CoPP） is correct？（）

• A、Control Plane Policing （CoPP） addresses the need to protect the management planes， ensuring routingstability， availability， and critical packet delivery.
• B、Control Plane Policing （CoPP） leverages MQC to define traffic classification criteria and to specifyconfigurable policy actions for the classified traffic.
• C、Control Plane Policing （CoPP） uses a dedicated "control-plane" command via the Modular QoS CLI （MQC）to provide filtering and rate limiting capabilities.
• D、Control Plane Policing （CoPP） uses "service policy" command under relevant interfaces to filter DOS packet to protect routing packets.
• E、Control Plane Policing （CoPP） protects the transit management and data traffic through the router.
