CONSO;
Regarding your 'A' scenario; Given that there is more 'remnant' of the inner part of the HS towards the aft, it almost appears that it could have 'peeled' off, front to back, or at least retained the join to the airframe for longer at the aft/trailing edge.
Could you perhaps set me straight on this if you have a moment? I would be interested to know why you have discounted it, if you see what I mean.
Especially given this photo where the panel corresponding to the leading edge appears to have been torn away:
