Why each option
The data plane, also known as the forwarding plane, is the component of a network device responsible for the actual movement of user data packets from an inbound interface to an outbound interface.
The signaling plane is a term often associated with establishing and managing connections or sessions, which is distinct from the function of forwarding user data.
The control plane is responsible for building and maintaining the forwarding tables (e.g., routing tables, MAC address tables), which are then utilized by the data plane, making them distinct functional components.
The data plane is interchangeably referred to as the forwarding plane because its primary function is to forward data packets through a network device based on the routing and switching decisions determined by the control plane.
The management plane handles administrative access, monitoring, and configuration of the network device itself, rather than the forwarding of user traffic.
