i dont know yet

Explanation:

• The Rh factor is a surface antigen (antigen D) on red - blood cell membranes. Most people worldwide are Rh⁺. For a person with type O blood lacking the Rh factor, the blood type is O⁻.
• Anti - Rh antibodies are not present in an Rh⁻ person's plasma without prior antigen exposure (such as through pregnancy with an Rh⁺ fetus or blood transfusion).

Answer:

Anti - Rh antibodies will be present in an Rh - negative person's plasma, even without antigen exposure.
