a. any bloood type
b. type a only
c. type b only
d. types a or b only

a. any blood type, but only if this has AB+ blood

Explanation:

Not all blood products can be transfused to any recipient. The compatibility between the donor's blood and that of the patient is essential.

A blood group is a way of grouping certain characteristics of blood based on the presence or absence of certain molecules, called antigens, on the surface of red blood cells. There are many blood groups, but among all of them, the groups belonging to the ABO and Rh system stand out for their importance at the time of transfusion.

ABO system

In this case the substance that determines the blood group is sugars, and according to its composition we find four groups: A, B, AB and O. In each of these groups the red blood cells have an antigen that differentiates them, group A has the antigen A, group B has antigen B, group AB has both antigens and group O has no antigen A, nor B.

The Rh system

In 1940 another group of antigens (D) were discovered that were called Rhesus factors (Rh factors) because they were discovered during experiments with apes of the Macaccus Rhesus type. According to this blood group, people with Rhesus factors in their blood would be classified as Rh positive; while those without the factors would be classified as Rh negative, and can only receive blood from Rh negative donors.

Compatibility

By combining these two systems we can arrive at a more detailed classification of the different blood types: A +, A-, B +, B-, AB +, AB-, O + and O-. Some of these blood groups are rarer than others.

Group   To whom can you donate                  From whom can you receive  

A +       Can donate to A + and AB +              Can receive from A ± and O ±  

A-        Can donate to A ± and AB ±              Can receive from A- and O-  

B +      Can donate to B + and AB +              Can receive from B ± and O ±

B-        Can donate to B ± and AB ±              Can receive from B- and O-    AB +    Can donate to AB +                                 Universal receiver                   AB-       Can donate to AB ±                     Can receive from A-, B-, AB- and O- O +      Can donate to A +, B +, AB + and O +      Can receive from O ±                O-            Universal donor                                       Can receive from O-
