   A network engineer is troubleshooting an OSPF adjacency issue between two routers connected via a satellite link with high latency (500 ms). The 'show ospf neighbor' command shows the neighbor in the Down state. The engineer verifies that the hello and dead intervals match on both routers. What is the most likely cause of the adjacency failure?

   • AThe OSPF MTU values are different on the two routers.
   • BThe OSPF dead interval is too short for the link latency.
   • CThe OSPF hello interval is too long for the link latency.
   • DThe OSPF authentication is misconfigured on one of the routers.
