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.
