The Correct Option is C
Solution and Explanation
EAN of $Co$ in $Na _{3}\left[ Co \left( NO _{2}\right)_{4} Cl _{2}\right]$
$=$ Atomic number of Co \pm oxidation state of Co
$+$ number of $e^{-}$ taken from $- NO _{2}$ and $- Cl$
$=27+3+(4+2)=36$
$=$ Atomic number of Co \pm oxidation state of Co
$+$ number of $e^{-}$ taken from $- NO _{2}$ and $- Cl$
$=27+3+(4+2)=36$

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.
