Answer 1

Right choice is (c) By administering anti-Rh antibodies to the mother

For explanation I would say: When a Rh-negative mother produces antibodies to an antigen in the blood of a Rh-positive fetus, it leads to a condition known as erythroblastosis fetalis. It can be avoided by administering anti-Rh antibodies to the mother.
