Wait, is this a trick question? What if the real answer is none of the above, and auto.create.topics.enable is just a lie to make us feel better about our Kafka deployments?

Haha, I bet the real answer is that the Kafka broker just automatically creates topics whenever it feels like it. You know, to keep us on our toes!

I'm not sure about C, but A, B, and D seem logical to me too.

I'm pretty sure C is also a valid answer. Altering partition count should trigger topic creation if it doesn't already exist.

I agree with Ilene, those scenarios make sense for auto topic creation.

A, D, and maybe B seem like the obvious answers here. Auto-creating topics is usually triggered by client requests or message production, not by consumers reading messages.
