Kubernetes - Operators and Custom Resources

AThe Subscription resource is missing the correct channel or package name

BThe Kubernetes cluster is offline

COperatorHub is not installed on the cluster

DYou used 'kubectl get packagemanifests' instead of 'kubectl apply'

Cluster offline would prevent all commands; OperatorHub is a service, not installed; wrong command usage is unrelated to Subscription creation.

The Subscription resource is missing the correct channel or package name -> Option A

Subscription details must be correct to install operator [OK]
