Correct Answer: 1, 2, 3 and 4. Steel manufacturing involves burning of coke which reacts with iron ore and releases iron and generates CO and CO2 gases. With this, the release of oxides of sulphur, nitrogen, carbon monoxide and carbon dioxide occurs, so pollutants like SOx and NOx are released. Hence options given in the question are all correct so D is the answer.
