(D) agglutination with anti-Rh antibodies agglutination with anti-B antibodies

Answer 1

Answer:

(B) agglutination with anti-A antibodies.

Explanation:

ABO blood type is based on two types of antigens: A and B antigens. The anti-A antibodies react with antigen A while anti-B antibodies react with antigen B.  

Blood type A has antigen A on the surface of its red blood cells and anti B antibodies in its plasma. Due to the presence of antigen A on its red blood cells, the blood type A shows agglutination with anti A antibodies.
