A Correct answer
Explanation

Rh incompatibility occurs when an Rh- mother is impregnated by an Rh+ father. The result can be an Rh+ baby. In such a case, the baby's Rh antigens will be perceived as foreign invaders, the way viruses or bacteria are perceived. The mother's blood cells attack the baby's as a protective mechanism, that can end up harming the child. This is called as erythroblastosis fetalis.
