A patch for a vulnerability has been released, and a DevOps team needs to update their running containers in Google Kubernetes Engine (GKE).
How should the DevOps team accomplish this?

A. Use Puppet or Chef to push out the patch to the running container. B. Verify that auto upgrade is enabled; if so, Google will upgrade the nodes in a GKE cluster. C. Update the application code or apply a patch, build a new image, and redeploy it. D. Configure containers to automatically upgrade when the base image is available in Container Registry.
