Answer:
Correct Answer: B
Solution:
[b] Rh factor was discovered by Karl Landsteiner.
A child of $ R{h^{+}} $ man will be $ R{h^{+}} $ whether the mother is $ R{h^{+}} $ or $ R{h^{-}} $ If the mother is $ R{h^{+}} $ then there will be no problem but if mother is $ R{h^{-}} $ so when the blood of $ R{h^{+}} $ child (in womb) mixes with the blood of $ R{h^{-}} $ mother then some antibodies in mother’s blood are formed against $ R{h^{+}} $ factor which coagulate the womb blood causing death.
If birth takes place then there is a possibility of child death in early years.
This in known as erythroblastosis foetalis.
In most cases, the 1st pregnancy may succeed but after that it fails.
