(Your configuration parameters for a Source connector and Connect worker are:• offset.

Apache Kafka Connect stores source connector offsets in a Kafka topic defined by the offset.storage.topic configuration. Since this property is explicitly set to connect-offsets, Kafka Connect will commit offsets to that topic, making Option C correct.

The offset.storage.replication.factor controls how many replicas the offsets topic will have. When this value is set to -1, Kafka Connect uses the broker’s default replication factor, as documented in the Kafka Connect worker configuration reference. Therefore, Option A is also correct.

Option B is incorrect because Kafka Connect does not use Kafka’s internal consumer offsets topic (__consumer_offsets). It always uses the configured offsets topic. Option D is incorrect because offset.flush.timeout.ms defines how long Connect will wait for offset commits to complete, not how long it waits before attempting a commit. The commit interval itself is controlled by offset.flush.interval.ms (60 seconds in this case).

Thus, the correct statements that match the expected behavior are A and C.
