What are the Rh antigens represented by?

The Rh antigens are primarily represented by the following: C, c, D, d, E, and e. The most significant among these is the D antigen, which is crucial for determining an individual's Rh status (positive or negative). When a person's blood type is tested for Rh factor, it is the presence or absence of the D antigen that is primarily assessed.

The other letters and combinations mentioned in the other choices refer to different blood group systems or antigens. For example, A and B are associated with the ABO blood group system, which classifies blood types into A, B, AB, and O based on the presence of specific antigens on red blood cells. The information given in choices involving A and B refers to different antigenic properties and are not linked to the Rh system itself.

Therefore, the correct choice encompasses all the relevant antigens specifically associated with the Rh blood group system, highlighting the variety and complexity of Rh antigens beyond just the D antigen.
