A production Deployment is running with 4 replicas. During a rolling update, the new pods fail readiness checks, causing the rollout to stall. The administrator needs to restore service immediately while preserving the ability to investigate the failed update. What should the administrator do?

Run `oc delete pods --all` to force recreation of all pods

Run `oc rollout undo deployment/app` to revert to the previous version

Run `oc rollout pause deployment/app` to stop the rollout

Run `oc scale deployment/app --replicas=0` and then scale back up
