A
Rh– female & Rh+ male
B
Rh+ female & Rh– male
C
Rh+ female & Rh+ male
D
Rh– female & Rh– male
Answer
Rh– female & Rh+ male
Explanation
Solution
Erythroblastosis fetalis is caused when an Rh- negative female (with Rh- negative blood type) is pregnant with an Rh- positive fetus (with Rh- positive blood type). If fetal Rh- positive blood enters the mother's bloodstream during pregnancy or childbirth, the mother's immune system may produce antibodies against Rh- positive blood cells, potentially causing hemolytic disease in the newborn.
So, the correct option is (A): Rh– female & Rh+male
