A) Regardless of what options are on offer, there shouldn't be any that introduce new uncertainties, so no "Negotiate a better deal with the EU, then leave" type option. "Deal" is WA+PD, as they stand.
C) But "no deal" MUST be more clearly worded, e.g. "Leave the EU without any deal."
D) Considering all the above,
Taking all of that together leaves us with something like:
B) Leave the EU with deal XYZ
C) Leave the EU without any deal
Not perfect. Not even particularly great. But taking the country as a whole, may provoke the least outrage.
(Personally I feel "no deal" has no place within a thousand miles of a second referendum, but...)
