B Correct answer
Explanation

Blood group O individuals can ONLY receive blood from other O group individuals because they have both anti-A and anti-B antibodies in their plasma. Receiving A or B blood would cause a dangerous transfusion reaction. While O is called the 'universal donor' (can give to anyone), they can only receive from other O donors. This is fundamental transfusion medicine.
