BIt locks the resources during the transaction.

CIt stores the final transaction state only.

DIt replaces the need for compensation transactions.

Final Answer:
It acts as a durable event log to coordinate transaction steps. -> Option A
Quick Check:
Kafka topic role = durable event log [OK]

Quick Trick: Kafka topics log events, not lock resources [OK]
