Solution

The correct option is D Nothing happens to Rh+ve person.
A Rh+ve person carries Rh antigen but no Rh antibodies. Rh antibodies are not present in blood but are produced by organism’s immune system during mixing of Rh positive and negative blood. A Rh-ve person does not carry Rh antigen or Rh antibodies and a blood transfusion from Rh-ve to Rh+ve won’t cause any immune reaction. Thus, the correct answer is option B.
