I practiced a question similar to this, and I think B is more about scaling rather than ZooKeeper's main functions.

I’m not entirely sure, but I feel like A could be right too since it seems related to managing cluster state.

I remember something about ZooKeeper being involved in leader election, so I think D might be one of the answers.
