Kafka Connect, when running in distributed mode, relies on three internal Kafka topics to share connector configurations, task statuses, and offset data among its worker processes. These topics are essential for fault tolerance and scalability. The default names for these topics are connect-configs (for storing connector and task configurations), connect-status (for storing connector and task state updates), and connect-offsets (for storing source connector offsets). Option A contains a common typo ("confiqs" instead of "configs"), but it clearly refers to the configuration storage topic.

B. connect-distributed: This refers to the distributed mode of operation for Kafka Connect workers, not an internal topic name.

D. connect-standalone: This refers to the standalone mode of operation for a single Kafka Connect worker, not an internal topic name.

1. Confluent Documentation, Kafka Connect, Configuration Properties: The official documentation lists the worker configuration properties that define the names of these internal topics.

config.storage.topic: "The name of the topic where connector and task configuration data are stored." The default value is connect-configs.

offset.storage.topic: "The name of the topic where connector offsets are stored." The default value is connect-offsets.

status.storage.topic: "The name of the topic where connector and task status data are stored." The default value is connect-status.

Source Reference: Confluent Documentation, "Worker Configuration Properties for Kafka Connect", Section: "Distributed Worker Configuration".

2. Apache Kafka Documentation, Kafka Connect 3.7: The official Apache Kafka documentation corroborates these configuration properties and their purpose for distributed workers.

Source Reference: Apache Kafka Documentation, Section 8.2 "Connect Configuration". The properties config.storage.topic, offset.storage.topic, and status.storage.topic are detailed for the distributed worker (connect-distributed.properties).
