Explanation:
The ABO blood group system classifies blood into four main types: A, B, AB, and O. This classification is based on the presence or absence of certain antigens on the surface of red blood cells. A person with an unknown blood group could have any of these four types.
In a blood transfusion, it is essential to match the blood types of the donor and recipient to prevent adverse reactions. The universal donor is type O, as it lacks A and B antigens, and the universal recipient is type AB, as it has both A and B antigens.
In this scenario, the person needs an immediate blood transfusion, and their friend has volunteered to donate blood without delay. Since the friend has a valid certificate of their blood type, it is assumed that they know their blood group.
The correct answer is option C, type O. This is because if the friend were type A, B, or AB, their blood would contain antigens that could react with the recipient's antibodies, causing a transfusion reaction. However, type O blood does not have antigens, so it can be safely transfused to anyone, regardless of their blood type. Therefore, type O blood is used in emergency situations when the recipient's blood type is unknown or unavailable.
