If type A contains both antigen A and anti B antibody. Anf Type O has neither antigen but both anti-A and anti-B antibodies.

When a person receives a blood transfusion, it often is Packed Red Blood cells suspended in CPDA (Citrate, Phosphate, Dextrose, and Andenine). This acts as an anticoagulant, plus helps the cells stay viable. Since Type O blood has neither Antii-A nor Anti-B antigen on the surface, it is safe to give to others.
However, plasma will have antibody. Therefore if a person was in need of Fresh Frozen Plasma (FFP); type O FFP has Anti-A, Anti-B in it. With that in mind, Type O is the universal recipient for Plasma.
Conversely A peson that has AB as a blood type; the red cells have Anti-A and Anti B on the red cell membrane, and no antibody in the plasma. So if that person must have Plasma, they must receive AB plasma.
About the only time I've ever seen Whole Blood transfused, is when a person has an Autologous unit, that is when the patient goes and has a unit of blood removed to be used on them for surgery. In the case of Whole Blood, where all constituents are present; Red Cells and Plasma, one must use Type specific; O must receive O, A must Receive A and the like.

Blood group O individuals do not have either A or B antigens on the surface of their RBCs, but their blood serum contains IgM antibodies against both A and B antigens. Therefore, a group O individual can only receive blood from a group O individual, but they can donate blood to individuals of any ABO blood group (ie A, B, O or AB).

Because Type O blood is doesnt have either A or B antibodies it works for all blood types. It will not hurt anyone to have type O blood because its universal.

O type blood is the universal donor because both type A and B have antibodies similar.
It doesn't cause an adverse reaction, so just go with it really.
I'd suggest looking it up in your science or biology textbook for their "textbook" answer.
