Q152 / 200 · NEET 2021 · Zoology

Persons with 'AB' blood group are called as "Universal recipients". This is due to:

  • A
    Absence of antigens A and B on the surface of RBCs
  • B
    Absence of antigens A and B in plasma
  • C
    Presence of antibodies, anti-A and anti-B, on RBCs
  • Correct answer
    D
    Absence of antibodies, anti-A and anti-B, in plasma

Solution

AB blood groups lack antibodies against antigen A & B, i.e. anti-A and anti-B, in plasma. Hence, they cannot target any particular blood group and have no chances of incompatibility reaction. Thus, called universal recipients.

Hence, the correct answer is option: 'D'.
