Answer Choices:
O
🧬Type O blood lacks both A and B antigens, making it less likely to cause an immune reaction when transfused into individuals of other blood types.
🛡️Because it has no surface antigens, the recipient's immune system is less likely to attack it.
🧪However, type O blood contains both anti-A and anti-B antibodies, which is why it can only receive blood from other type O donors.
💉Due to its universal compatibility, type O negative is especially critical in emergencies when blood type is unknown.
📌Core Message
Type O is the universal donor because it has no A or B antigens, minimizing transfusion reactions in recipients of any blood group.
