Show answer and explanation

Correct answer: (C) P-III, Q-IV, R-I, S-II

Explanation

Nitric acid is made by Ostwald's process (III). Phosphoric acid is made by the Haifa process (IV). Stearic acid is made by the Twitchell process (II), a fat splitting process. That leaves the Trona process (I) for the potassium chloride in the list. Only option C has P-III, S-II and Q-IV.
