Question

Theoretically, a person with type AB blood should be able to receive a. type \(B\) and type \(A B\) blood. b. type \(\mathrm{O}\) and type \(\mathrm{B}\) blood. c. type A and type O blood. d. All of these are correct.

Short answer

The correct answer is option a. Theoretically, a person with type AB blood can safely receive type A, type B, and type AB blood, but not type O blood.

Step-by-step solution

Recall properties of blood groups

To solve this problem, we need to recall the primary blood groups and their compatibility. The blood groups are A, B, AB, and O, and they are determined by the antigens and antibodies present in the blood. Here are the properties of each blood group: - Group A: has antigen A, and anti-B antibodies - Group B: has antigen B, and anti-A antibodies - Group AB: has both antigens A and B, but no antibodies - Group O: has no antigens, but has both anti-A and anti-B antibodies. Remember, a person can safely receive blood from a donor if the donor's blood does not cause any immune reaction in the recipient's blood.

Option a: Type B and Type AB blood

We need to check if a person with type AB blood can safely receive type B and type AB blood. - If the donor has type B blood, it means they have antigen B, and anti-A antibodies. Since a recipient with type AB blood has no antibodies, this will not cause an immune reaction. Therefore, a person with type AB blood can safely receive type B blood. - If the donor has type AB blood, it means they have both antigens A and B, and no antibodies. Since the recipient also has the same blood type, there will be no immune reaction. Therefore, a person with type AB blood can safely receive type AB blood. So, option a is correct.

Option b: Type O and Type B blood

We need to check if a person with type AB blood can safely receive type O and type B blood. - We already checked that a person with type AB blood can receive type B blood. - If the donor has type O blood, it means they have no antigens, but both anti-A and anti-B antibodies. Since the recipient with type AB blood has both antigens A and B, the anti-A and anti-B antibodies in type O blood will cause an immune reaction. Therefore, a person with type AB blood cannot safely receive type O blood. So, option b is not correct.

Option c: Type A and Type O blood

We need to check if a person with type AB blood can safely receive type A and type O blood. - If the donor has type A blood, it means they have antigen A, and anti-B antibodies. Since the recipient with type AB blood has no antibodies, there will be no immune reaction. Therefore, a person with type AB blood can safely receive type A blood. - As we discussed earlier in option b, a person with type AB blood cannot safely receive type O blood. So, option c is not correct.

Option d: All of these are correct

Based on the analysis in options a, b, and c, we know that a person with type AB blood can safely receive type A, B, and AB blood, but cannot receive type O blood. Therefore, not all options are correct.

Conclusion

The correct answer is option a. Theoretically, a person with type AB blood can safely receive type A, type B, and type AB blood, but not type O blood.
