Explanation:
The ABO blood group system is based on the presence or absence of two antigens (A and B) on the surface of red blood cells. These antigens determine the blood type of an individual:

- Type A: has A antigen on the red blood cells
- Type B: has B antigen on the red blood cells
- Type AB: has both A and B antigens on the red blood cells
- Type O: has neither A nor B antigens on the red blood cells

When a person with an unknown blood group needs immediate blood transfusion, it is important to use compatible blood to avoid adverse reactions. As per the ABO system, a person with type O blood is considered a universal donor because their blood does not have A or B antigens that can trigger an immune response in the recipient.

Therefore, in the given scenario, the donor friend who has a valid certificate of his own blood type must have type O blood, as he is willing to donate blood without delay. This makes him a suitable donor for the person with an unknown blood group who needs immediate transfusion.
