What is the next step a vSphere administrator would take to successfully provision the data disk?

A virtual machine needs to add a 4TB disk. The storage administrator has already created
and presented a 4TB LUN to the ESXi host. A 500GB VMFS5 datastore already exists on
the host. What is the next step a vSphere administrator would take to successfully provision
the data disk?

A.
Expand the VMFS volume to 4TB. Create a virtual compatibility mode RDM mapping to
the 4TB LUN.

B.
Expand the VMFS volume to 4TB. Create a physical compatibility mode RDM mapping to
the 4TB LUN.

C.
Create a virtual compatibility mode RDM mapping to the 4TB LUN.

D.
Create a physical compatibility mode RDM mapping to the 4TB LUN.
