B should be ok.

vSphere does not support automatic datastore conversions from NFS version 3 to NFS 4.1. If you want to upgrade your NFS 3 datastore, the following options are available:

You can create a new NFS 4.1 datastore, and then use Storage vMotion to migrate virtual machines from the old datastore to the new one.

Use conversion methods provided by your NFS storage server. For more information, contact your storage vendor.

Unmount from one version and then mount as the other.

The question itself is incorrect.

NFS3 doesn’t support kerberos protocol within VMware.

Upgrade to NFS4.1 requires upgrade to the NFS NAS in the backend from NFS3 to NFS4.1 with kerberos.
