The answer is b). This is most useful to the initiator for learning
what the correct range is, and this detail used to be specified
in SCSI-2. I think that section has been neutered in SCSI-3 so
this detail isn't specified any more.

I suggest looking in the direct access device model section.
That is where the information used to be. Maybe the information
is still there somewhere.
