A Correct answer
Explanation

Rh type mother-fetus incompatibility occurs only when an Rh+ man fathers a child with an Rh- mother. The first time an Rh- woman becomes pregnant, there usually are not incompatibility difficulties for her Rh+ fetus. However, the second and subsequent births are likely to have life-threatening problems for Rh+ fetuses.
