You create a Deployment with 2 replicas in a Google Kubernetes Engine cluster that has a single preemptible node pool. After a few minutes, you use kubectl to examine the status of your Pod and observe that one of them is still in Pending status:

What is the most likely cause?

• A.The node pool is configured with a service account that does not have permission to pull the container image used by the pending Pod.
• B.The pending Pod's resource requests are too large to fit on a single node of the cluster.
• C.The pending Pod was originally scheduled on a node that has been preempted between the creation of the Deployment and your verification of the Pods' status. It is currently being rescheduled on a new node.
• D.Too many Pods are already running in the cluster, and there are not enough resources left to schedule the pending Pod.
