b) Rh+ man and Rh+ woman
c) Rh– man and Rh– woman
d) Rh– man and Rh+ woman
Answer »Answer: (a)
Rh factor was discovered by Karl Landsteiner. A child of $Rh^+$ man will be $Rh^+$ whether the mother is $Rh^+$ or $Rh^–$.
If the mother is $Rh^+$ then there will be no problem but if the mother is $Rh^–$ so when the blood of $Rh^+$ child (in the womb) mixes with the blood of $Rh^–$ mother then some antibodies in the mother’s blood are formed against $Rh^+$ factor which coagulates the womb blood causing death.
If birth takes place then there is a possibility of child death in the early years. This is known as erythroblastosis foetal. In most cases, the first pregnancy may succeed but after that, it fails.
