[单选题] A network planning diagram shows a large internetwork with many routers. The configurations show that OSPF has been enabled on all interfaces, I P addresses correctly configured, and OSPF workinG. For which of the following cases would you expect a router to create and flood a Type 2 LSA?（）

A、When OSPF is enabled on a LAN interface, and the router is the only router connected to the subnet. B、 When OSPF is enabled on a point - to -point serial link, and that router has both the higher router ID and higher interface IP address on the link. C、When OSPF is enabled on a Frame Relay point - to - point subinterface, has the lower RID and lower subinterfa ce IP address, and otherwise uses default OSPF configuration on the interface. D、When OSPF is enabled on a working LAN interface on a router, and the router has been elected BDR. E、None of the other answers is correct.
