The correct answer is b. Synthetic Anti-D clones.In the Rh blood group system, the presence or absence of the Rh factor (also known as the D antigen) on the surface of red blood cells determines whether a person's blood is Rh positive or Rh negative. To determine a person's Rh blood group, synthetic Anti-D clones are used. These clones are antibodies that specifically target the D antigen. When mixed with a person's blood, if the D antigen is present, the Anti-D clones will cause agglutination (clumping) of the red blood cells, indicating that the person's blood is Rh positive. If there is no agglutination, the person's blood is Rh negative.Saline solution (option a) is simply a salt solution and does not contain any antibodies. Plasma-substituting solutions (option c) are used to treat conditions such as shock or blood loss, but they do not contain antibodies to determine blood groups. Synthetic anti-A and anti-B clones (option d) are used to determine blood groups according to the ABO system, not the Rh system.
