Understanding Rh Blood Grouping
The correct answer to the statements regarding Rh blood grouping is option 'A'. Here's a detailed breakdown of each statement:
Statement A: Rh factor is an antigen present on the surface of RBCs
- This statement is correct. The Rh factor, specifically the D antigen, is a protein that can be present on the surface of red blood cells (RBCs). People who have this antigen are classified as Rh positive, while those who do not are Rh negative.
Statement B: Rh positive individuals have Rh antibodies naturally present in plasma
- This statement is incorrect. Rh positive individuals typically do not have Rh antibodies in their plasma unless they have been sensitized to Rh positive blood, such as through a blood transfusion or during pregnancy.
Statement C: Nearly 80% of Indians are Rh positive
- This statement is correct. Studies indicate that a significant majority of Indians, approximately 80%, are Rh positive.
Statement D: Rh negative blood can be donated to Rh positive individuals
- This statement is correct. Rh negative blood can be safely donated to Rh positive individuals without causing an immune response.
Statement E: Rh incompatibility can cause haemolytic disease of the newborn
- This statement is also correct. If an Rh negative mother carries an Rh positive fetus, her body can produce antibodies against the Rh factor, potentially leading to hemolytic disease in the newborn.
In conclusion, since statements A, C, D, and E are correct, option 'A' is indeed the correct choice.

Which of the following statements regarding Rh blood grouping are corr...
The correct answer is Option A - A, C, D and E only
A is correct: the Rh factor refers to the presence of the D antigen on the membrane of red blood cells (RBCs), so it is an antigen located on the RBC surface.
B is incorrect: anti-Rh (anti-D) antibodies are not normally present; they are produced only after sensitisation (exposure by transfusion or pregnancy). Naturally occurring antibodies are characteristic of the ABO system, not the Rh system.
C is correct: the prevalence of Rh positivity in the Indian population is approximately 80% (commonly reported as around this value), so most individuals are Rh positive.
D is correct: blood lacking the D antigen (Rh negative) can be given to an Rh positive recipient because it will not introduce the D antigen that could trigger an anti-D immune response in the recipient.
E is correct: Rh incompatibility can lead to haemolytic disease of the newborn when an Rh negative mother is sensitised to fetal Rh positive red cells and produces anti-D IgG that cross the placenta and destroy fetal RBCs in subsequent pregnancies.
