Which action should an administrator take to increase the size of a VMFS5 datastore from 2TB to
32TB?
A.
Dynamically expand the original LUN and add a second share for the NFS datastore
B.
Dynamically expand the original LUN and increase the size of the VMFS datastore
C.
Dynamically expand the original LUN and add extents to the VMFS datastore
D.
Dynamically expand the original LUN and add extents to the NFS datastore

N.B.
“Add(ing) extents” is the old way (VMware version <5.0)
Not completely correct statement.
Until Vsphere 4. You could only increase a datastore by adding extents.
From Vsphere 4 and up GROWING an EXISTING EXTENT is possible.

VMFS Datastores in vSphere 4.x and 5.x can be increased in size by adding a new extent on a DIFFERENT storage DEVICE (spanning), or by increasing the size of the EXISTING storage DEVICE and then GROWING the existing datastore extent to fill that available adjacent capacity.
So in this case the EXISTING extent can GROW.
NOTE: Each LUN must contain only one VMFS datastore!
DING!
B – however, must be offline

Bob, the question is about a datastore, that can be online while expanding.
I guess you are talking about a single VMDK that goes beyond 2TB, for that the VM needs to be powered off. Your link points to info about a VMDK betond 2TB, not a datastore.
A : Dynamically expand the original LUN and add a second share for the NFS datastore
It talks about VMFS5 datastore, not NFS… -_-
