HPA shows unknown CPU target

A HorizontalPodAutoscaler never scales and shows the output below. What is the most likely cause?

NAME   REFERENCE        TARGETS         MINPODS   MAXPODS   REPLICAS
api    Deployment/api   <unknown>/70%   2         10        2

A.There are already too many replicas running in the namespaceB.The Service type should be LoadBalancer instead of ClusterIPC.The container image is too large to pull fast enough to scaleD.Pods have no CPU requests, or metrics-server is missing
