Question

the blood of a person with blood type b would agglutinate if exposed to which blood type? a a b b c o

Explanation:

Blood type B has B antigens on red blood cells and anti - A antibodies in the plasma. When exposed to blood type A (which has A antigens), the anti - A antibodies in the type B blood will react with the A antigens, causing agglutination. Blood type B (same type) has no reaction as there are no foreign antigens. Blood type O has no A or B antigens, so no reaction with anti - A antibodies in type B blood.

Answer:

A. A
