Explanation / Answer

answer : e. The number of ligand atoms that are attached to the metal.

explanation :

coordination number means number of donar atoms that are directly attached to central ion directly attached to central atom or ion .

statement 2 is also very close to the answer but that is not correct in case of polydentate ligands. polydentate ligands having 2 or more donar atoms so it is not suitable .
