It Cannot be A, because To form an OSPF adjacency, routers must match on the Area ID, subnet, Hello and Dead timers, and authentication settings Just modifying Hello timer doesn't help and it says nothing about Dead Timer It has to be D
"without forming adjacency" are the key words. To make two OSPF routers become neighbors without forming a full adjacency on a broadcast network, you must prevent both of them from being elected as the Designated Router (DR) or Backup Designated Router (BDR). This is achieved by setting their OSPF interface priority to 0.
The question can go back and forth but there is one simple fact...the ONLY way a neighbour relationship can be formed in the first place is ONLY when the hello interval timers are matched. For this simple reason alone, I will go with A.
