Statement A: Concentrated HNO₃ decomposes interfering NaCN and Na₂S into volatile HCN and H₂S gases, which are boiled off.

Statement B: Both CO₂ and SO₂ react with lime water to form insoluble precipitates (CaCO₃ and CaSO₃), turning it milky.

Statement C: Fuming HNO₃ is a strong oxidizing agent that completely oxidizes organic sulfur into sulfate ions (SO₄²⁻).

Statement D: Sodium fusion converts the covalent nitrogen and carbon of the organic compound into ionic sodium cyanide (NaCN or CN⁻).
