Which approach handles a poison event that repeatedly crashes the processor?

1. A Increase throughput units
2. ✓ B Catch the exception, write the event to a dead-letter store, checkpoint past it, and continue (correct answer)
3. C Delete the partition
4. D Reduce retention

Shortcut: Event Hubs has no built-in dead-lettering. The consumer must isolate the bad event itself and advance the checkpoint, otherwise the partition stalls permanently.
