While troubleshooting this problem, you issue the "show ip ospf interface Ethernet 0"command on each router. The output from these commands is displayed below:What is the underlying cause of the routers failing to become adjacent?（）A. The OSPF area is misconfigured.B. The priority on TK2 should be set lower.C. The cost on TK2 should be set lower.D. The hello and dead timers are misconfigured.E. You need to add a backup designated router to the network.F. The OSPF process ID numbers do not match.
