Hypothalamus
Basal ganglia
Spinal cord
Hippocampus

Correct Answer is B
Explanation
a) Mom is Rh-positive and the fetus is Rh-positive: No issue arises because the mother's immune system recognizes the Rh antigen as self.
b) Mom is Rh-negative and fetus is Rh-positive: If the mother is Rh-negative and the first fetus is Rh-positive, the mother's immune system may become sensitized during delivery. In subsequent pregnancies with Rh-positive fetuses, maternal anti-Rh antibodies (IgG) can cross the placenta and attack fetal RBCs, causing hemolytic disease of the newborn (erythroblastosis fetalis).
c) Mom is Rh-negative and fetus is Rh-negative: No immune response is triggered; both are Rh-negative.
d) Mom is Rh-positive and fetus is Rh-negative: No risk; maternal antibodies are not formed against Rh-negative cells.
