Refer to the exhibit. R5 is the current DR on the network, and R4 is the BDR. Their interfaces are flapping, so a network engineer wants the OSPF network to elect a different DR and BDR. Which set of configurations must the engineer implement?

A. R4(config)#interface gi0/0
R4(config-if)#ip ospf priority 20
R5(config)#interface gi0/0
R5(config-if)#ip ospf priority 10
B. R5(config)#interface gi0/0
R5(config-if)#ip ospf priority 120
R4(config)#interface gi0/0
R4(config-if)#ip ospf priority 110
C. R3(config)#interface gi0/0
R3(config-if)#ip ospf priority 255
R2(config)#interface gi0/0
R2(config-if)#ip ospf priority 240
D. R2(config)#interface gi0/0
R2(config-if)#ip ospf priority 259
R3(config)#interface gi0/0
R3(config-if)#ip ospf priority 256
