Suggested Answer:A🗳️
Most traditional devices use a distributed architecture, in which each control plane is resided in a networking device. Therefore, they need to communicate with each other via messages to work correctly. In contrast to distributed architecture, centralized (or controller-based) architectures centralizes the control of networking devices into one device, called SDN controller.
A is correct.
Explanation:
In traditional network architecture, the control plane and data plane are integrated. Any changes to the system are dependent upon configuring physical network devices, the protocols, and software they support. You can perform only limited changes to the overall system as the network devices bottleneck logical network traffic flows. Devices function autonomously and offer limited logical awareness toward the wider network.
In contrast, SDN decouples the Control Plane from the Data Plane and centrally integrates the network logic at the controller level. A controller separated between the two Planes logically centralizes the network intelligence such that users can choose which programmable features to move from network devices onto the application server or controller.

Please reread answer C. Centralized Management is definitely not a strength of traditional networks...
And Controller-based decouple control plane and data plane from a single device. So A is the only one that makes sense.
The only one that is correct is the A. Because only a Controller Based Network have The Data Plane and Control Plane that are separated from a unique "brain entity".
