The correct option is A Only $B^{-}$

Correct option: C.

Rh factors are an antigens which are present/ absent in individuals. If a person with Rh- blood group receives Rh+ blood this will cause a delayed immune response causing agglutination of the transfused blood cells. Whereas individuals with blood group with Rh- factor can be transfused to the same blood group( both Rh-and Rh+) and AB+.

O- blood group is known as universal donor and AB+ is known as universal receiver.
