Organization vDCs provide an environment where virtual systems can be stored, deployed, and operated!
Question is: What is a Provider vDC?
So answer should be B.
A Provider vDC is used to offer a single type of compute resources and a single type of storage resources. This means that Provider vDCs are created for segmenting resources based on resource characteristics (Tiering) or quantity of resources (Capacity). Basically a Provider vDC will function as a SLA construct in the vCloud. At the vSphere layer a VMware vSphere Cluster or Resource Pool can be used to provide the Provider vDC raw Virtual Infrastructure resources.
