Blood type AB+ is considered the universal recipient because it can receive all 4 types of blood and type O- is the universal donor everyone can receive this blood type.

Type O is the safest blood type to use in an emergency and therefore the first one to run out. People with blood type O should please become blood donars!

Comes from German "ohne" ("without") [antigens]. The question is poorly phrased.
