Final answer:
Blood type O has no antigens and is considered a universal donor, while blood type AB makes no antibodies, making it a universal recipient. The correct pair is d) O; AB.
Step-by-step explanation:
The correct answer to the question is: Blood type O contains no antigens, while blood type AB makes no antibodies. Therefore, the answer is d) O; AB.
People with type O blood lack both antigens A and B on their erythrocytes but carry both anti-A and anti-B antibodies in their blood plasma. Hence, they are considered universal donors.
On the other hand, individuals with type AB blood have both antigens A and B on their erythrocytes, and no anti-A or anti-B antibodies in their blood plasma, which leads to them being known as universal recipients.
The correct answer to the question is: Blood type O contains no antigens, while blood type AB makes no antibodies. Therefore, the answer is d) O; AB.
