HPA shows unknown CPU

A HorizontalPodAutoscaler targets 70% CPU, but kubectl get hpa shows "<unknown>/70%" and it never scales. Metrics-server is running. What is the most likely cause?

A.The Deployment has too many replicas alreadyB.The pods do not set CPU resource requests, so utilization as a percentage cannot be calculatedC.HPA only works with memory metricsD.The cluster autoscaler is disabled
