SSCE VCE Biology Immunity and Disease Response: If the red blood cells of a bloo

Question

If the red blood cells of a blood donor clot when they enter a recipient patient, the patient will die. The blood of both recipient and donor has to be tested and typed. Humans are divided into four different groups with regard to the ABO blood-grouping system. The characteristics of these groups are summarised in the following table.

| protein on red blood cells | group A | group B | group AB | group O |
|-----------------------------|---------|---------|----------|---------|
|                             | A       | B       | A and B  | neither A nor B |
| antibodies in plasma        | antibodies to B protein | antibodies to A protein | no antibodies to either A or B protein | antibodies to both A and B protein |

A transfusion would be safe if a
A. group A person received blood from a group B person.
B. group B person received blood from a group O person.
C. group O person received blood from a group A person.
D. group A person received blood from a group AB person.
