C Correct answer
Explanation

Blood group O individuals do not have either A or B antigens on the surface of their RBCs, but their blood serum contain IgM anti A antibodies and anti B antibodies against the A and B blood group antigens. Therefore, an individual of blood group O can receive blood only from a blood group O individual, but can donate blood to individuals of any ABO blood group.
