Final answer:
The OSPF Neighbor State represents the different stages of establishing and maintaining neighbor relationships between routers in computer networks.
Step-by-step explanation:
The subject of this question is Computers and Technology. Specifically, it is about the OSPF Neighbor State in computer networks. OSPF is a routing protocol used by routers to exchange routing information. The different neighbor states in OSPF represent the different stages of establishing and maintaining neighbor relationships between routers. In the given scenario, where a router has sent Hello packets but has not received any from the neighbor router with their RID (Router ID), the neighbor state would be Init. In this state, the router is waiting to hear from the neighbor and establish a two-way communication. Therefore, the correct answer is B) Init.
