Correct answer · Option C
A-(IV), B-(I), C-(III), D-(II)
Explanation
In Dumas method, nitrogen is collected as \( \text{N}_2 \) gas (A-IV); Chlorine is precipitated as \( \text{AgCl} \) (B-I); Sulphur is precipitated as \( \text{BaSO}_4 \) (C-III); Phosphorus is ignited to \( \text{Mg}_2\text{P}_2\text{O}_7 \) (D-II).
