D1, 2, 5 only ✓ Correct
Correct answer: (D) 1, 2, 5 only — The commission credited option (d), so that is the answer.
Explanation
★The commission credited option (d), so that is the answer.
★Soot and fly ash are recognised air pollutants.
★The commission's key grouped fog with these as well.
★Fog is naturally an aerosol and does not usually pollute, so the item is disputed.
★Still, the official answer is the fog, soot and fly ash grouping.
★Hence, per the commission, 1, 2 and 5 is keyed.
