You have an existing topic t1 that you want to delete because there are no...

Kafka supports topic deletion via the kafka-topics.sh tool if the broker property delete.topic.enable=true. This is the recommended and cleanest method to delete a topic and its data from the cluster.

From Kafka documentation:

“To delete a topic, use kafka-topics.sh with --delete flag, provided delete.topic.enable is set to true on the broker.”

A → Correct: Official method.

B → Misunderstood use of null keys (used for compaction).

C → Not recommended; causes inconsistent state.

D → Deletes consumer state, not the topic itself.
