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

What can you deduce from the show command on router R6?
- A. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.3.
- B. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.
- C. The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.
- D. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.5.
