It is a weak D red cells having a reduced amount of D antigen.
Rh blood type is determined by the presence or absence of the D antigen. People who are Rh positive have the D antigen and those that are Rh negative lack this. Some people have a variant of the D antigen, called Du. Presence of Du antigen causes lab results to report the blood type as Rh negative, although the patient behaves as an Rh positive would. Du negative means a "true Rh negative" result.
It is the equivalent to Rh negative blood. D is the antigen present on commonly termed Rh+ red cells, and the D antigen is missing on D-negative blood.
antigen D is the most important
There are about 45 different Rh antigens, the most important of which is the D-antigen.
Blood type D is not one of the four main blood type groups. There is a D antigen that is part of the Rh antigen system, but there is not a blood type group called blood type D.

The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.
Basically, Group A Rh (D) +ve blood type has antigen A and antibody B
