Answer: Use the `kubectl scale deployment` command with the `--replicas 4` parameter.
The correct command to increase the number of replicas to 4 is `kubectl scale deployment` with the `--replicas 4` parameter. This command scales the deployment to the specified number of replicas. The `--deploy` parameter does not exist in the `kubectl scale deployment` command. For more details, refer to the Kubernetes documentation on deployments: [https://kubernetes.io/docs/concepts/workloads/controllers/deployment/](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/).
