B
O
C
AB
D
A
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
In blood transfusion, the recipient's blood group should be compatible with the donor's blood group. Blood group AB is a universal recipient, meaning a person with AB blood group can receive blood from any group (A, B, AB, or O). Therefore, if the accident victim was successfully transfused with blood from the father whose blood group is AB, the blood group of the accident victim could be AB.
