Which statement accurately describes the O blood type?

• A. Contains antigen A and B
• B. Contains only antigen B
• C. Does not have antigen A or B
• D. Can only donate blood to O blood type

Answer: (C)

The O blood type is characterized by the absence of both A and B antigens on the surface of red blood cells. This means that individuals with O blood type do not produce A or B antigens, making their blood type universal in terms of donation to other blood types. This lack of antigens is key because it allows O blood type individuals to donate blood to any other type without triggering an immune response, which happens when incompatible antigens are present. In contrast, other blood types, such as A, B, or AB, contain specific antigens that O does not, which is why they could avoid both A and B antigens and thus prevent any potential adverse reactions in recipients. The understanding of the O blood type's characteristics is fundamental in blood transfusion practices and compatibility analyses.
