Oh boy, I can just picture the intern panicking and frantically hitting the restart button. 'Please don't crash, please don't crash!' Gotta keep that Kafka cluster healthy, folks!

Hmm, I'm going with B. As long as the replication factor is 3, the other brokers should have the data covered. Though I bet the intern's getting an earful for that little incident.

C, the broker will crash. I mean, come on, deleting all the data? That's a surefire way to make a broker go down in flames. Literally.

D! The broker will start without any data, and if it becomes a leader, we'll have data loss. Ouch, that's a tough situation. Gotta be extra careful with those brokers.

I think the correct answer is B. The broker will start, but it won't be online until all the data it needs is replicated from the other leaders. Losing a broker is never good, but at least the data is safe.
