   A developer is deploying a containerized application to GKE. The application occasionally becomes unresponsive due to a deadlock, but it does not exit. The developer wants to ensure that the container is automatically restarted when this happens. Which configuration should be added to the deployment manifest?

   • AA readiness probe that checks an HTTP endpoint and removes the pod from the Service on failure.
   • BA liveness probe that checks an HTTP endpoint and restarts the container on failure.
   • CA resource limit on the container that causes the pod to be evicted when memory usage is high.
   • DA startup probe that checks an HTTP endpoint and delays the liveness probe until the app is ready.
