Q. No.Persons with AB blood type can:
| 1. | donate blood to persons with all blood types as neither A nor B antigens are present on their RBCs |
| 2. | receive blood from persons with all blood types as both A and B antigens are present on their RBCs |
| 3. | receive blood from persons with all blood types as neither A nor B antigens are present on their RBCs |
| 4. | receive blood from persons with all blood types as neither anti-A nor anti-B antibodies are present on his blood plasma |
Consider the given two statements:
I. Group O blood can be donated to persons with any other blood group and hence O group individuals are called universal donors.
II. Both anti-A and anti-B antibodies are present in the plasma of a person with blood group O.
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. Both I and II are incorrect

1. Presence of antibodies, anti-A, and anti-B, on RBCs
2. Absence of antibodies, anti-A, and anti-B, in plasma
3. Absence of antigens A and B on the surface of RBCs
4. Absence of antigens A and B in plasma
