The correct answer is The stone is an offering that helps bridge the distance between the siblings.
Explanation:
In the excerpt, readers can understand there is some distance between the two siblings. The stone helps bridge it since both of them refer to objects or persons that are important for one or both of them; for example, Rider mentions the chain where the stone would be hanging, something important for her sister; on the other hand, Margie assigns Rider his Dad characteristic's and all the actions seen as one create a new bond between the two siblings.
