Referring to the exhibit, you are configuring an OSPF network. All OSPF adjacencies come up and
stay stable. But neither R1 nor R2 has the prefix 200.200.200.200/32 in its routing table. What is
causing this problem?

A.
R2 does not have the export policy for prefix 200.200.200.200/32.

B.
R1 does not have routes to network 172.10.1.0/24.

C.
R2 is BDR on both network 172.10.1.0/24 and 172.20.1.0/24.

D.
The router ID of R1 is the same as the router ID of R3.
