Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Someone with Type A blood also has ____
A
Type A antibodies
B
Type B antibodies
C
both Type A & B antibodies
D
neither Type A nor B antibodies
Explanation: 

Detailed explanation-1: -Thus, a group A individual will have anti-B antibodies and a group B individual will have anti-A antibodies. Blood group O is common, and individuals with this blood type will have both anti-A and anti-B in their serum.

Detailed explanation-2: -Because your blood contains the A marker, it makes B antibodies. If B markers (found in type B or type AB blood) enter your body, your type A immune system gets fired up against them. This means that you can only get a transfusion from someone with A or O blood, not from someone with B or AB blood.

Detailed explanation-3: -Your ABO blood type is based on the presence or absence of the A and B antigens on your red blood cells. The A blood type has only the A antigen and the B blood type has only the B antigen. The AB blood type has both A and B antigens, and the O blood type has neither A nor B antigen.
