Which of the following three commands could be configured on each router to correct this problem?（）

A. RouterC(config - if)#ip ospf network broadcast RouterD(config - if)#ip ospf network broadcast

B. RouterC(config - if)#ip ospf network point - to - point RouterD(config - if)#ip ospf network point - to - point

C. RouterC(config - router)#neighbor 10.100. 100.4 RouterD(config - router)#neighbor 10.100.100.3
