The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?

AThe adjacency state is two way because both routers have received a database description packet.

BThe adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.

CThe adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.
