If the broker deletes all messages with the key K, does that mean I can just delete all my problems? Sign me up for that A option!

B, a Runtime exception? That's like saying the producer has a 'self-destruct' mode. Nah, I'm sticking with C, sounds the most logical to me.

D? Really? That's like saying the Kafka broker has a magical 'ignore' button. I'm going with C, gotta be the safest bet here.

Hmm, I was leaning towards A, but now I'm not so sure. Guess I'll have to double-check my Kafka knowledge before choosing an answer.

I'm not sure, but I think D) The message will get ignored by the Kafka broker makes sense because the value is null.
