Concept:The Rhesus (Rh) factor is a blood protein, and Rh incompatibility between mother and baby can cause a serious condition in the child.
Explanation:A person with Rh protein in the blood is Rh-positive, while someone without it is Rh-negative.
If an Rh-negative woman marries an Rh-positive man, the baby may inherit the Rh-positive factor from the father.
During the first pregnancy, the mother may produce antibodies against the Rh-positive blood of the baby.
In a second pregnancy with an Rh-positive baby, these antibodies can cross the placenta and destroy the baby's red blood cells.
This leads to a condition called erythroblastosis fetalis, which causes severe sickness and can result in the death of the offspring.
Answer:Option B — it will result in sickness and probably death of the offspring.
