Which of the following statements is NOT correct about the immunological incompatibility between mother and baby?

Select one:

a. The baby's Rh+ blood will never get in contact with the mother's Rh- blood during the pregnancy as the placenta does not allow fetal blood cells to mix with the maternal blood.

b. If the baby is Rh+ and the mother is Rh-, it does not pose a problem as long as this is the mother's first pregnancy.

c. When the mother has Rh- blood, anti-Rh antibody injection is given during her pregnancy to prevent any antibodies from forming.

d. Rh- blood has no rhesus factor proteins and therefore will produce antibodies for the Rh factor when exposed to Rh+ blood.

Rh Blood Group:

The human blood group system discovered by Landsteiner and Weiner in the 1940s is named the Rh blood group system. It is determined concerning the presence or absence of D antigen proteins. These antigens are present on the surface of erythrocytes. The term Rh was designed as its determination test was done on the group of rhesus monkeys. The existence of D or Rh antigen in the blood makes an individual Rh-positive, while its absence makes the individual negative.
