RouterAdebug ip ospf events OSPF events debugging is on RouterA 04:43:16: OSPF: Rcv pkt from 10.3.0.2, Ethernet0/1, area 0.0.0.1 mismatch area 0.0.0.2 in the header 04:43:19: OSPF: Rcv hello from 10.100.100.3 area 0 from Ethernet0/0 10.1.0.1 04:43:19: OSPF: End of hello processing Refer to the exhibits. What can be done to fix the problem?（）

A. Change router B E0/1 interface to area 0.

B. Change router A interface E0/1 to area 0.0.0.2.

C. Configure the E0/1 i nterfaces of router A and router B to be in area 0.

D. Shut down the E0/1 interfaces in router A and router B as OSPF does not allow "back doors" between areas.

E. Remove the E0/1 interfaces in router A and router B from the OSPF process. Use static rou tes to route data directly from router A to router B to avoid passing data through router C in area 0.
