Answer 2

The blood group 'O' contains no antigens but both a and b antibodies are present.

Explanation:

• The blood group has been classified according to the ABO system.
• In this 'O' blood group is also known as universal donor as it does not contain antigens. When transfused it won't receive any rejection from the receiver patient.
• It contains anti A and anti B antibodies in the plasma.
• The blood group 'AB' has no antibodies in it, therefore it is a universal receptor.
