The Correct Option is C
Solution and Explanation
$ {EAN= Z - (O.N.) + 2 \times (CN.)}$
???????????????????[Z= atomic number,
????????????O.N. = Oxidation number,
????????C.N. = Coordination number]
??= 27 - 3 + 2 $\times $ 6 = 36
???????????????????[Z= atomic number,
????????????O.N. = Oxidation number,
????????C.N. = Coordination number]
??= 27 - 3 + 2 $\times $ 6 = 36

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
