D is the correct answer. A DR or a BDR router will always need to reach a full state relationship with all neighbours (DROther included!) for correct operation. A 2-way state will only be considered correct and stable between two DROther routers.
Answer is D - Full
"In this state, routers are fully adjacent with each other. All the router and network LSAs are exchanged and the routers' databases are fully synchronized."

The exercise asks for the adjacency status of the DR (designated router) working properly, correct answer is D. Full.
"A designated router (DR), assumes the role of pseudonode (virtual router) to reduce adjacencies avoiding overload, it obtains a FULL status with all neighbors, with BDR (FULL/BDR) and DROTHER (FULL/DROTHER). BDR receives backup information, so BDR also gets FULL status with all neighbors (FULL/DR) (FULL/DROTHER). DROTHER gets FULL status with DR (FULL/DR) and BDR (FULL/BDR) , but only with other DROTHERs (DROTHER with DROTHER) we have 2-way adjacency status (2WAY/DROTHER)."
The "2-way" state is reached when a router detects its OSPF neighbor on the network. This happens after the establishment of the "2-way" adjacency, the routers can exchange OSPF information, but still do not have complete information from the neighbor's link-state database.

sorry "Full is the normal state for an OSPF router"
In this state, routers are fully adjacent with each other. All the router and network LSAs are exchanged and the routers' databases are fully synchronized.
