Refer to the exhibits. You are verifying your OSPF implementation, and it does not seem to be functioning properly. What can you conclude from the exhibit and the show running - configuration command output? （）

A、The OSPF areas are not configured correctly.

B、The wildcard masks for the 10.x .x.x networks are incorrect.

C、The 172.16.x.x networks need to be connected to area 0 using virtual links.

D、The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to 172.16.0.0/16 and data is being "black holed."

E、There is not enough information to make a determination.
