Which action can be taken on a multiaccess segment with OSPF speakers to reduce the performance impact during widespread convergence events?

Which action can be taken on a multiaccess segment with OSPF speakers to reduce the performance impact during widespread convergence events?
A. Separate the network into multiple areas for each new multiaccess segment.
B. Enable LSA throttling in the core to slow link state advertisement updates during times of network instability.
C. Ensure that the elected DR or BDR router can support high-volume convergence events.
D. Verify that fewer than 50 OSPF speakers are on the segment.
