A ,B ,or A and B but there is also O

Explanation:

A antigens are present on some humans red blood cells these humans have blood type A, A antigens are Anti-B , or the total opposite of B and AB blood.

B antigens are present on some humans red blood cells these humans have blood type B, B antigens are Anti-A, the total opposite of A and AB blood.

A and B antigens are present of some humans red blood cells these humans have type AB blood, These blood cells are not Anti A or B, meaning if that person received donated blood they would be considered a universal recipient because they can receive type A or B blood.

Some people are type O where they have no antigens in their blood whatsoever not A or B, they also have no antibodies in their blood, they can only have O blood but they are universal blood donors.
