Correct Answer: Option C
Explanation

The stillbirth of a second child that is Rh-positive in an Rh-negative woman can occur due to the clumping of fetal blood caused by the production of Rh antibodies in the mother's immune system during a previous pregnancy with an Rh-positive baby. This condition, known as hemolytic disease of the newborn, can be prevented with appropriate medical interventions like Rh immunoglobulin injections.
