Suggested Answer: A 🗳️
The management plane is used in order to access, configure, and manage a device, as well as monitor its operations and the network on which it is deployed. The management plane is the plane that receives and sends traffic for operations of these functions. You must secure both the management plane and control plane of a device, because operations of the control plane directly affect operations of the management plane. This list of protocols is used by the management plane:
✑ Simple Network Management Protocol
✑ Telnet
✑ Secure Shell Protocol

I'm not sure but B is the best choice, but enable CoPP is not bad but it's complicated procedure to implement not feature to implement.
