The correct answer is: Sodium pentacyanonitrosyl ferrate (III)
Sodium nitroprusside has the formula \(\mathrm{Na}_2\left[\mathrm{Fe}(\mathrm{CN})_5 \mathrm{NO}\right]\). It is named based on the ligands attached to the iron center. The nitrosyl group ($\mathrm{NO}$) and cyanide ($\mathrm{CN}$) ligands are named accordingly, and the oxidation state of iron in this complex is +3. Therefore, the correct name is Sodium pentacyanonitrosyl ferrate (III).
