View answer and explanation

Correct option: C

{\mathrm{K}_3}[\mathrm{Fe}{\left( {\mathrm{CN}} \right)_6},\;

the ligand has satisfied only the secondary valency of ferric ion

The correct answer is C. In

{\mathrm{K}_3}[\mathrm{Fe}{\left( {\mathrm{CN}} \right)_6}]

, the ligand (CN-) satisfies only the secondary valency (coordination number) of the ferric ion (Fe3+).
