   • Brequests.storage: 50Gi, accessModes: ReadWriteMany, no storageClassName

   A PersistentVolumeClaim (PVC) was created with a requested size of 10Gi and is bound to a PersistentVolume (PV) provisioned by the 'standard' StorageClass. The application now needs 20Gi. The administrator edits the PVC to request 20Gi, but the PVC remains at 10Gi. What is the most likely reason for this?

   • AThe PV must be manually resized before the PVC can be expanded.
   • BThe StorageClass 'standard' does not have allowVolumeExpansion set to true.
   • CThe PVC is still bound to the PV, so it cannot be resized.
   • DThe PVC must be deleted and recreated with the new size.
