Refer to the exhibit. The partial configuration for an OSPF ASBR and an Area 0 ABR is shown. Assume the OSPF configurations throughout the network are operable. Which statement about these configurations is true? （）A. The ASBR route - maps are basically useless, because there are no deny prefix - lists.B. LSA Type 5s wil l not be received by the ABR from the ASBR.C. The OSPF backbone will not learn any RFC 1918 addresses.D. The matched prefix - list addresses will be given a metric of 255, which is essentially unreachable.
