Answer: Activate auto-repairing for the nodes to allow Kubernetes engine to replace unhealthy nodes.
The correct answer is **C** because enabling auto-repairing for the nodes enhances resiliency and high availability by allowing Kubernetes engine to automatically replace nodes that fail health checks. This feature is crucial for maintaining a healthy, running state of your cluster without manual intervention. - **Option A** is incorrect as auto-upgrades are related to updating node versions, not ensuring node health. - **Option B** is incorrect because auto-healing for managed instance groups is not applicable to Kubernetes clusters. - **Option D** is incorrect as there is no auto-healing feature for nodes in Kubernetes. For more details, refer to the [GCP documentation on Kubernetes Auto-Repairing](https://cloud.google.com/kubernetes-engine/docs/how-to/node-auto-repair).
