Which Blood Group in human is Universal Donar?

O Group

The correct answer is Option (3) – O Group

The blood group in humans that is considered the Universal Donor is O Group.

Explanation:

• In blood transfusions, compatibility between the donor's blood and the recipient's blood is crucial to prevent adverse reactions.
• Type O negative (O-) blood is considered the universal donor because individuals with this blood type can donate blood to individuals of any blood type (A, B, AB, or O) without causing an immune reaction.
• People with O negative blood are often referred to as universal donors, making their blood valuable in emergency situations when the recipient's blood type may not be immediately known.

In summary, O Group (especially O negative) is considered the universal donor blood type.
