Which metrics should be set to zero to ensure a healthy Kafka cluster and data consistency?

The correct answer is C. Under-replicated partitions, offline partitions, and ISR (In-Sync Replicas) shrink rate. A healthy cluster maintains full replication and stable ISR membership. Zero under-replicated and offline partitions indicate full availability, while a zero ISR shrink rate shows replicas are not frequently falling out of sync, ensuring data consistency.
