Which of the following conditions cause erythroblastosis foetalis?
- A Both mother and foetus \(Rh ^{\text {+ve }}\)
- B Mother Rhtve and foetus \(Rh ^{-v e}\)
- C Mother \(Rh ^{-v e}\) and foetus \(Rh ^{\text {+ve }}\)
- D Both mother and foetus \(Rh ^{-v e}\)
Answer & Solution
Correct Answer
(C) Mother \(Rh ^{-v e}\) and foetus \(Rh ^{\text {+ve }}\)
Step-by-step Solution
Detailed explanation
Option (3) is correct answer because Erythroblastosis foetalis occurs only when foetus is Rhtve and mother is Rh-ve. During Ist delivery, if Rhtve foetal blood mixes with mother's blood, antibodies are produced in mother's body against Rh antigen.
