B) the A antigen
C) the B antigen
D) the D antigen
E) anti-D

Accepted Answer

Rh antigen is also known as the D antigen. It is a protein on the surface of red blood cells and is important for blood typing. If an individual lacks the D antigen, they are Rh negative, and if they have the D antigen, they are Rh positive. This is important in blood transfusions and in pregnancy, as an Rh-negative mother may have complications if carrying an Rh-positive baby.
