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.
