The Correct Option is C
Solution and Explanation
A neutral complex is a complex ion which have no charge on it. Among the given options $\left[ Pt \left( NH _{3}\right)_{2} Cl _{2}\right]$ is a neutral complex. The type of complexes in other options are as follows:
(a) $\left[ Fe \left( H _{2} O \right)_{6}\right] Cl _{3}$ - cationic complexes
(b) $\left[ Ni \left( NH _{3}\right)_{6}\right] Cl _{6}$ - cationic complexes
(d) $K \left[ Ag \left( CN _{2}\right)\right]$ - anionic complexes
(a) $\left[ Fe \left( H _{2} O \right)_{6}\right] Cl _{3}$ - cationic complexes
(b) $\left[ Ni \left( NH _{3}\right)_{6}\right] Cl _{6}$ - cationic complexes
(d) $K \left[ Ag \left( CN _{2}\right)\right]$ - anionic complexes

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.
