Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?()

A. All OSPF implementations must have at le ast one interface in area 0.

B. You are attempting to run in the broadcast mode over an NBMA interface.

C. Both routers are configured to function as a BDR; therefore, there is no DR router.

D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.

E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.
