C). Motherly
Susan Sowerby - The mother of Martha and Dickon (as well as of twelve other children), Susan Sowerby functions as a symbol for the concept of motherhood itself. She is all-nurturing, all-knowing, and appears dressed in a hooded blue cloak like that of the Christian Virgin Mary (the mother of Jesus Christ). Both Mary and Colin express the wish that she were their mother; stories of her sustain each of them before their respective transformations.
