I think B is the best choice. With mountains you have rocks. If you have enough you can build a pretty good shelter just using rocks. Maybe start a rock town with rock friends and rock children. It will be a nice little ending.
The only thing ending with this plan is your lives. From hypothermia.
Everyone here seems to have forgotten that you have been walking through the snows of Mt. Coronet for
five days straight with only a half-assed bow and arrow to protect yourself with. The sea won't keep you warm. It's winter. The mountain will keep you warm, if by warm you mean cold. The village has houses, people, and warmth (real warmth). Desperate times call for desperate measures. Head to the village.
