Why each option
VMFS datastores are deployed on block storage, which can be provided by Fibre Channel or iSCSI protocols.
Fibre Channel is a block-level storage protocol that provides high-speed data transfer between servers and storage devices, making it suitable for VMFS datastores.
NFS is a file-level storage protocol, not block-level, and while it can be used for virtual machine storage, it cannot be used to create a VMFS datastore.
iSCSI is a block-level storage protocol that encapsulates SCSI commands over standard TCP/IP networks, allowing servers to access storage devices as if they were local, and is commonly used for VMFS datastores.
CIFS (Common Internet File System) is a file-level storage protocol primarily used for shared folders on Windows systems and is not suitable for VMFS datastores.
SMB (Server Message Block) is a file-level storage protocol, an evolution of CIFS, and is not used for creating VMFS datastores.
