Which storage option would best meet company objectives?

A company wants to increase disk capacity for their VMware vSphere environment Management mandates that:

(1) VMotion must work in this environment

(2) the existing LAN infrastructure must be used

(3) the storage must support VMFS volumes

Which storage option would best meet company objectives?

A.
NFS

B.
Fibre Channel

C.
iSCSI

D.
SATA

Overview of Using ESX/ESXi with a SAN
Using ESX/ESXi with a SAN improves flexibility, efficiency, and reliability. Using ESX/ESXi with a SAN also supports centralized management and failover and load balancing technologies. The following are benefits of using ESX/ESXi with a SAN:
You can perform live migration of virtual machines using VMware Vmotion.

Therefore this option would meet requirement (1) VMotion must work in this environment

iSCSI SANs use Ethernet connections between computer systems, or host servers, and high- performance storage subsystems. The SAN components include host bus adapters (HBAs) or Network Interface Cards (NICs) in the host servers, switches and routers that transport the storage traffic, cables, storage processors (SPs), and storage disk systems

Therefore this option would meet requirement (2) the existing LAN infrastructure must be used

Use the vSphere Client to set up a VMFS datastore in advance on any SCSI-based storage device that your ESX/ESXi host discovers. A VMFS datastore can be extended over several physical storage extents, including SAN LUNs and local storage. This feature allows you to pool storage and gives you flexibility in creating the storage volume necessary for your virtual machine.

Therefore this option would meet requirement (3) the storage must support VMFS volumes
