The correct response is D. OSPF DR and BDR election on a broadcast network is influenced by interface priority. To force different routers to win, the flapping routers should be given priority 0 or lower priority while the desired routers have higher priority, followed by a neighbor reset if needed. For Cisco CCNA 200-301 v1.1, the important point is the mechanism, not a generic description of the technology. Changing unrelated process values or router IDs alone does not reliably replace an already elected DR/BDR on a live segment. When this appears in a network, the symptom normally confirms the answer: the route installed, the state selected, the packet forwarded, the wireless client behaviour, or the management workflow will follow this rule. That is why this answer is the best fit for the scenario and not just a plausible networking term.
