Which Kubernetes resource type is appropriate for stateful workloads like databases that require stable network identities and persistent storage?

1. A Deployment
2. B ReplicaSet
3. C DaemonSet
4. ✓ D StatefulSet (correct answer)

Shortcut: StatefulSets provide stable, unique pod names (pod-0, pod-1), stable DNS, and ordered deployment/scaling. Each pod gets its own PersistentVolumeClaim.
