     #correct_answer: "A PVC deletion may stall or fail if the associated volume is deleted manually before the PVC API object is removed using `kubectl`. This creates an inconsistent state where the PVC is still referenced but the underlying volume no longer exists. To resolve this, you can list volume attachments with `kubectl get volumeattachments`, describe the attachment with `kubectl describe volumeattachments <volume-name>`, edit it to remove the `external-attacher` finalizer, and then delete the PVC with `kubectl delete pvc <pvc-name>`."
