B.

No

Suggested answer: A

Explanation:

= A persistentVolumeClaim (PVC) is a request for storage by a user. It is similar to a Pod.Pods consume node resources and PVCs consume PV resources1.A PVC can specify a storage class, which is a way of requesting a certain quality of service for the volume2.If the storage class is empty, it means the PVC does not have any specific storage class requirements and can be bound to any PV that satisfies its size and access mode3. However, if there is no existing PV that matches the PVC's requirements, the PVC remains unbound until a suitable PV becomes available.This can happen either by manual provisioning by an administrator or by dynamic provisioning using StorageClasses1.Reference:
