Explanation

Northbound APIs let applications and orchestration tools interact with the SDN controller, so they are associated with application-plane communication, automation, and integration/data exchange. They are commonly implemented with REST-style interfaces. OpenFlow is a southbound protocol used between the controller and forwarding devices in the data plane, so any option describing controller-to-data-plane communication or OpenFlow belongs to southbound APIs instead.
