Step-by-Step Solution

Solution:

Step 1: Identify correct CLI command for topic config
To alter topic config, use kafka-topics.sh with --alter and --config flags.
Step 2: Check options
kafka-topics.sh --alter --topic my-topic --config cleanup.policy=compact --bootstrap-server localhost:9092 uses correct syntax. kafka-topics.sh --create --topic my-topic --compaction enabled --bootstrap-server localhost:9092 uses invalid flag. kafka-configs.sh --set --topic my-topic --property cleanup.policy=compact uses wrong tool. kafka-console-producer.sh --topic my-topic --config cleanup.policy=compact is for producing messages.
Final Answer:
kafka-topics.sh --alter --topic my-topic --config cleanup.policy=compact --bootstrap-server localhost:9092 -> Option B
Quick Check:
Correct CLI syntax = kafka-topics.sh with --alter and --config [OK]
