I agree with that. And when a consumer in a consumer group shuts down, it will also trigger partition rebalance.

Aha! I knew those were the right answers. Partition rebalancing is such a key part of Kafka consumer group management. Can't believe anyone would think adding a broker would trigger it.

Ha! I almost picked C, but then I remembered that adding a new consumer doesn't necessarily mean the partitions will be rebalanced. Gotta think this one through carefully.

Hmm, I think B, D, and E are the correct answers. Increasing partitions and adding a consumer should trigger a rebalance, and removing a broker or a consumer dropping out would definitely do it too.
