Carrier Sense Multiple Access with Collision Detection is the most correct answer. CSMA/CD works by checking for active communications and attempting to transmit when clear. If a collision occurs, then it will use the back-off timer. CSMA with Collision Avoidance is incorrect. Since it is not conventionally possible to determine if or when a device is transmitting, collisions are inevitable. To counter this, a timer mechanism is in place to regulate transmissions and will back-off pre-emptively, actively avoiding as many collisions as it can. Multiprotocol Label Switching is incorrect; this relates to labelling switched traffic of different protocols and has no relevance to collision aversion. Open Shortest Path First is incorrect; OSPF helps find the shortest path through a network for fast and efficient delivery of data and has no relevance to collision aversion.
