The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Rh Factor**: The Rh factor is a protein that can be present on the surface of red blood cells. If a person has this protein, they are considered Rh positive (Rh+), and if they do not, they are Rh negative (Rh-). 2. **Identifying the Parents' Rh Status**: In the scenario presented, we have a father who is Rh positive and a mother who is Rh negative. This combination is crucial because it leads to the potential for Rh incompatibility. 3. **Fetal Rh Status**: The child can inherit the Rh factor from the father. Since the father is Rh positive, he can either be homozygous (Rh+/Rh+) or heterozygous (Rh+/Rh-). In either case, there is a possibility that the child will be Rh positive. 4. **Rh Incompatibility**: If the child is Rh positive and the mother is Rh negative, the mother's immune system may recognize the Rh positive blood cells as foreign. This can lead to the production of anti-Rh antibodies by the mother. 5. **Mechanism of Antibody Production**: Normally, during pregnancy, the placental barrier prevents the mixing of maternal and fetal blood. However, during delivery, if there is a rupture of placental blood vessels, fetal blood can enter the mother's circulation. This exposure can trigger the mother's immune response. 6. **Consequences of Antibody Formation**: The anti-Rh antibodies produced by the mother can cross the placenta and enter the fetal circulation. This can lead to hemolytic disease of the newborn, which can cause severe anemia, jaundice, and in severe cases, can be fatal. 7. **Conclusion**: Therefore, the combination of an Rh positive father and an Rh negative mother poses a significant risk for child death due to Rh incompatibility. Thus, the correct answer to the question is that the chances of child death occur in the marriage of an Rh positive man and an Rh negative woman.
