Correct answer and explanation

Correct answer: Person having O group blood

Explanation: āœ… Correct Answer: A) Person having O group blood šŸ“š Explanation: A person with blood group 'O' (specifically O negative) is considered a 'universal donor'. This is because their red blood cells do not have A or B antigens, so their blood can be safely given to people of any other blood group. In emergencies, O negative blood is often used when there is no time to test the patient's blood type. This group is highly valuable for blood banks and hospitals.
