The correct Answer is:
To solve the question regarding child death in marriages based on Rh compatibility, we need to understand the concept of Rh factor and its implications during pregnancy. Here’s a step-by-step breakdown: ### 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 Rh positive (Rh+); if not, they are Rh negative (Rh-). 2. **Identifying the Combinations**: - The question provides four combinations of Rh factors between a man and a woman: - A) Rh+ man and Rh+ woman - B) Rh+ man and Rh- woman - C) Rh- man and Rh- woman - D) Rh- man and Rh+ woman 3. **Analyzing Each Combination**: - **A) Rh+ man and Rh+ woman**: Both parents are Rh positive, so the child will also be Rh positive. There is no risk of Rh incompatibility. - **B) Rh+ man and Rh- woman**: The child can be either Rh+ or Rh-. If the child is Rh+, the Rh- mother may develop antibodies against the Rh+ blood cells, leading to complications in future pregnancies (hemolytic disease of the newborn). - **C) Rh- man and Rh- woman**: Both parents are Rh negative, so the child will also be Rh negative. There is no risk of Rh incompatibility. - **D) Rh- man and Rh+ woman**: The child can be either Rh+ or Rh-. However, if the child is Rh+, the Rh- father does not pose a risk of developing antibodies, as he is not carrying the Rh+ antigen. 4. **Conclusion**: - The combination that poses the highest risk for child death due to Rh incompatibility is **B) Rh positive man and Rh negative woman**. If the child inherits the Rh+ factor from the father, the mother’s immune system may attack the child’s blood cells, leading to serious complications. ### Final Answer: **B) Rh positive man and Rh negative woman**
