B, it seems like that this would be the best answer, my reason; "'Noble men and noble women, ambassadors and centurions, ladies and tradeswomen, and babies who have never seen a cow.'
'Well, yes; perhaps; particularly centurions."'
'Who don't know anything of us, and where it comes from; or think how we two drove miles across the moor to-night in the rain that it might reach 'em in time?'"
Hope this helps, and hope that this is right!
