Point out the wrong statement.
(a) The Kafka cluster does not retain all published messages
(b) A single Kafka broker can handle hundreds of megabytes of reads and writes per second from thousands of clients
(c) Kafka is designed to allow a single cluster to serve as the central data backbone for a large organization
(d) Messages are persisted on disk and replicated within the cluster to prevent data loss
