D. NFS
Correct Answer: B

VMFS is used as the storage management interface for block-based disk storage, which includes Fibre Channel SAN.
Incorrect Answers:

C: Virtual Raw Device Mapping (RDM) lets the RDM behave as if it were a virtual disk, to allow the use of features such as snapshotting and cloning.
D: Network File System (NFS) is used in a Network-attached Storage (NAS) configuration.
