answer is B and C: notice the limitations on RDMS but the real flag is it does NOT NOT NOT support greater than 2 TB. see below for futher details

Why switch to VMFS-5?

Improved scalability and performance.
Does not use SCSI-2 Reservations, but uses the ATS VAAI primitives.
Uses GPT (GUID Partition Table) rather than MBR, allowing for pass-through RDM files greater than 2TB.
VMFS5 in ESXi 5.5 now supports upto 62 TB VMDK and non-passthrough RDM. For more information, see Support for virtual machine disks larger than 2 TB in vSphere 5.5 (2058287).
Newly created VMFS-5 datastores use a single block size of 1MB.
Supports very small files (2TB. Non-pass-through RDMs and virtual disk files are still limited to 2TB -512B in 5.0 and 5.1. In ESXi 5.5, support for non-passthrough RDMs has been increased to 62TB.
Passthrough RDMs are supported up to 64TB in size.
Both upgraded and newly-created VMFS-5 volumes supported the larger Passthrough RDM size.
There is no space requirement for upgrading from VMFS3 to VMFS5.

Note: The actual maximum size of a LUN will depend on the capabilities of RAID controller/adapter driver that is used on the vSphere host.

For vSphere 5.x storage configuration maximums pertaining to 2TB LUN support please review:
