   An application is deployed to AKS using a Deployment manifest. The team needs to update the container image to a new version and ensure the rollout is gradual, with the ability to roll back if the new version fails. The current manifest is stored in a Git repository. What is the recommended approach?

   • AUse kubectl set image to change the image directly in the cluster without updating the manifest.
   • BEdit the image tag in the Deployment manifest, commit the change, and use kubectl apply to update the deployment.
   • CDelete the existing deployment and create a new one with the updated image tag using kubectl create.
   • DRun kubectl rollout restart to force the deployment to pull the latest image from the registry.
