Correct answer & explanation

Verify current DR/BDR roles with show ip ospf interface

The correct order ensures that the OSPF DR/BDR election is properly influenced. First, verify the current DR/BDR roles using show ip ospf interface. Next, set the OSPF priority on the desired router to a higher value than the current DR. Then, clear the OSPF process on all routers to force a new election. After that, verify the new DR/BDR roles have been elected as expected. Finally, confirm that adjacencies are formed with the new DR/BDR.
