[单选题] Refer to the exhibit. Will redistribute d RIP routes from OSPF Area 2 be allowed in Area 1? （）

A、RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.  B、Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.  C、Redistrib uted RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.  D、Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.  E、Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.
