An Rh-Negative Mother Will Need a Special Treatment If She

An Rh-negative mother will need a special treatment if she gives birth to an Rh-positive baby. The treatment involves the destruction of any stray blood cells from the baby that pass into the mother's bloodstream. Why is this necessary?

A) The mother's immune system will attack the Rh-positive cells and produce antibodies that will attack a fetus in a subsequent pregnancy.
B) The mother's immune system will attack her own blood cells and the cells in the fetus of a subsequent pregnancy.
C) Without this treatment, the mother's immune system will attack only her own blood cells.
D) Without this treatment, antibodies will be formed in breast milk, which could harm the baby.
