Answer»

The CORRECT choice is (C) Link-state RESPONSE

For explanation: The five types of OSPF packets are: Hello, Database description, Link-state request, Link-state update, and Link-state ACK. There is no Link-state response PACKET; the NEIGHBOR router sends a Link-state update packet as a response to the Link-state request packet if there is an update in the routing table.
