You are deploying a new version of your application to a multi-zone Google Kubernetes Engine (GKE) cluster. The deployment is progressing smoothly, but you notice that some Pods in a specific zone are experiencing higher error rates. You need to selectively roll back the update for the Pods experiencing errors with minimal impact to users. What should you do?

A. Scale down the Pods in the affected zone. Redeploy the new version of the application. B. Drain the affected nodes. Redeploy the new version of the application to the remaining nodes. C. Modify the Deployment to use the Pod template from the previous version of your application. Perform a rolling update to replace the Pods in the affected zone. D. Use the kubectl rollout undo command to roll back the entire deployment. Redeploy the new version of the application, excluding the affected zone.
