Explanation
The correct answer is option 2 i.e Alfred Werner.
In 1898, Alfred Werner propounded the theory that the ions or groups bonded to the metal by secondary bonding have spatial arrangements corresponding to different characteristic coordination numbers.
This theory, known as Werner's Coordination Theory, was groundbreaking in the field of inorganic chemistry and laid the foundation for modern coordination chemistry. Werner's work earned him the Nobel Prize in Chemistry in 1913.
