Answer:
(D) Rh negative and carrying Eh positive foetus.
Answer:
Rh incompatibility occurs when a pregnant woman whose blood type is Rh-negative is exposed to Rh-positive blood from her fetus, leading to the mother's development of Rh antibodies
a) she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign. Her antibodies will pass into the baby's bloodstream and attack those cells. This can make the baby's red blood cells swell and rupture.
b)the mother is Rh-negative, her immune system treats Rh-positive fetal cells as if they were a foreign substance. The mother's body makes antibodies against the fetal blood cells. These antibodies may cross back through the placenta into the developing baby. They destroy the baby's circulating red blood cells.
c)A woman with Rh-negative blood has nothing to worry about if their baby is also Rh-negative, and a woman with Rh-positive blood need not worry at all. Problems arise only with Rh-negative mothers and Rh-positive babies. Usually the first pregnancy goes fine. It's a subsequent Rh-positive baby who may be at risk.
d) During pregnancy, red blood cells from the unborn baby can cross into the mother's blood through the placenta. If the mother is Rh-negative, her immune system treats Rh-positive fetal cells as if they were a foreign substance. The mother's body makes antibodies against the fetal blood cells.
