"You must create a storage policy for the placement of container images. You select the storage policy to apply to the image registry when you enable the embedded Harbor registry." Page 268 of vCF : install and manage

D: Prerequisites To enable the embedded Harbor Registry, you must have enabled Workload Management and deployed a Supervisor Cluster. In addition, create a storage policy for placement of container images. This storage policy is used to provision persistent volumes to use as the backing store for the container images in the registry. https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-AE24CF79-3C74-4CCD-B7C7-757AD082D86A.html

B is right vSphere with Tanzu embeds an instance of Harbor that you can use as the private container registry for vSphere Pods and for pods running on Tanzu Kubernetes clusters. For more information, see Enable the Embedded Harbor Registry on the Supervisor Cluster. https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-376FCCD1-7743-4202-ACCA-56F214B6892F.html D is right so we need to have first a Tanzu Enabled Cluster (Answer B) https://core.vmware.com/?share=isim_demo3364&title=enabling-the-embedded-harbor-image-registry

D is the correct Answer. https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-AE24CF79-3C74-4CCD-B7C7-757AD082D86A.html/https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-with-tanzu-services-workloads/GUID-EB11DFDE-6ED4-4864-9E60-669F50D64397.html. In both 7.0/8.0, WLD needs to be enabled and supervisor cluster deployed as prerequisite and need Storage policy which is used as storage class for pvc part of harbor
