Answer 1

The correct answer is Landsteiner.

Key Points

Karl Landsteiner discovered the major human blood groups - A, B, AB, and O in 1901.
He found that blood transfusions between individuals of the same group did not lead to the destruction of blood cells, while those between different groups did.
His work laid the foundation for safe blood transfusions.
For this discovery, he was awarded the Nobel Prize in Physiology or Medicine in 1930.
