A 25-year-old woman, gravida 1, para 0, who is Rh-negative, delivers a full-term Rh-positive neonate. The mother is given prophylactic anti-Rho(D) immune globulin immediately post partum. During her second pregnancy 3 years later, she is screened each trimester for Rho(D) antibodies. An indirect antiglobulin test done during the third trimester indicates the presence of anti-Rho(D) antibodies in her serum. Which of the following is the most likely mechanism for the occurrence of these maternal antibodies?
A) Anamnestic production of maternal anti-Rho(D) immunoglobulin
B) Intrauterine transplacental fetal-maternal hemorrhages during the second pregnancy
C) Residual circulating prophylactic anti-Rho(D) immunoglobulin
D) Transplacental passage of fetal IgG anti-Rho(D) antibodies
