Question

Which of the following situations will be fatal to the first foetus?

• A. Rh negative male marries Rh positive woman
• B. Rh positive male marries Rh negative woman
• C. Rh positive male marries Rh positive woman
• D. Rh negative male marries Rh negative woman

Answer 1

The correct option is B Rh positive male marries Rh negative woman

When both the mother and her fetus are Rh- (dd), the birth will be normal. 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.

So, the correct option is 'Rh positive male marries Rh-negative woman'.
