Which response by the nurse is most appropriate when the mother, concerned about her unborn daughter developing DMD, states that her brother and son have DMD?

D "If your unborn child is a girl, she may carry the gene, but she will not develop DMD." B "Your brother and son have DMD; it's unlikely that you'll have another child with DMD." A "You already have one child with muscular dystrophy; it's unlikely you'll have another." C "As many as one-third of children born with DMD have no family history of the disease."
