Solution

For blood transfusions, it is necessary that the blood type of donor and recipient must match.

The plasma of the recipient consists of certain antibodies, and it is important that the donor blood has the same antibodies.

If the antibodies differ, the recipient will recognise them as foreign and will attack the donor's blood cells.
