Question 1. The best answer is C - antigen on the red blood.

The ABO  blood classification is based on the red blood cells. In summary:

1. blood type A has antigen A  on the red cell membrane.

2. blood type B has antigen B on the red cell membrane.

3. blood type AB has both antigen A and B on the cell membrane.

4. blood type O has no antigen at all on the red cell membrane.

Question 2. the best answer is b - transportation of oxygen.

Sickle cells have an abnormal type of hemoglobin that is unable to  carry oxygen  in the same capacity that normal, healthy hemoglobin does.
