"Which of the following determines an individual's blood type? Presence of specific antigens on the surface of their red blood cells. Presence of specific antigens in their blood plasma_ Presence of specific antibodies on the surface of their red blood cells: Presence of specific antibodies in their blood plasma:"
Adi S.
Blood type depends on the presence of surface antigens on the RBC. If you have type O blood, antibodies will attack type A and B surface antigens. Plasma contains Anti-A and Anti-B antibodies. These specific antibodies determine blood type.

Blood Antigens Human blood can contain the A antigen, the B antigen, both the A and B antigens, or neither antigen. A third antigen, called the Rh antigen, is important in human reproduction, and again may or may not be present in an individual. Blood is called type A-positive if the individual has the A and Rh but not the B antigen. A person having only the A and B antigens is said to have type AB-negative blood. A person having only the Rh antigen has type O-positive blood. Other blood types are defined in a similar manner. Identify the blood types of the individuals in regions (a)–(h) below.
