The Correct Option is A

Solution and Explanation

Ionic conductivity depends upon the number of ions produced in aqueous solution. $K_4[Fe(CN)_6]$ produces maximum number of ions, i.e. 5
$\underbrace{ 4K^++ [Fe(CN)_6]^{4-} }_{Total\, 5\, ions}$

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.
