Vedclass · Answer

(A) In the $ABO$ blood grouping system,blood group '$O$' is characterized by the absence of both '$A$' and '$B$' antigens on the surface of red blood cells $(RBCs)$.However,the plasma of individuals with blood group '$O$' contains both anti-$A$ (antibody '$a$') and anti-$B$ (antibody '$b$') antibodies.Therefore,the correct statement is that there is an absence of antigens but a presence of '$a$' and '$b$' antibodies.
