The Correct Option is C
Solution and Explanation
Some salts containing two different metallic elements give test for only one of them in solution, such salts are complex salts.
For example, $K _{4}\left[ Fe ( CN )_{6}\right]$ is a complex salt.
In aqueous solution, it will dissociate into $K ^{+}$ions and $\left[ Fe ( CN )_{6}\right]^{4-}$ ions.
The aqueous solution of $K _{4}\left[ F e ( CN )_{6}\right]$ will give test for $K ^{+}$ions only. It will not give test for $F e ^{2+}$ 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.
