As saffie said, a lot of people would do a combination of B and C, because while they may or may not have moved on they still want their spouse to pine for them for the rest of their lives, because that was the deal, right?
If you're angling for "I know someone whose spouse did "B" and does that mean they might still want the marriage" my opinion is "you can't tell". They might still want the marriage, they might want to cake-eat, or they might really have moved on and just be the petty type. Nor should it matter to the spouse. They should continue to GAL and if WA comes back great (if LBS still wants them) and if not they'll still be fine.
