{'chemical fertilizers': [1, 0, 0, 1], 'phosphoric acid fertilizer': [0, 0, 0, 1], 'ammonia': [0, 1, 0, 2], 'sulphur': [0, 0, 0, 2], 'natural gas': [2, 0, 2, 3], 'oil refineries': [2, 0, 3, 3], 'urea': [5, 1, 4, 10], 'market': [0, 0, 1, 0], 'raw material': [2, 1, 2, 8]}
In India, the retail price of chemical fertilizers is not market-driven. Instead, it is monitored and controlled by the government. So, statement 1 is incorrect.
Statement 2 is correct. Urea is produced by the reaction of ammonia and carbon dioxide. And in turn, ammonia is produced from natural gas. Therefore, ammonia, an input for urea, is indeed produced from natural gas.
Statement 3 is also correct. Sulphur is a raw material for phosphoric acid fertilizer and it is indeed a by-product of oil refineries. When crude oil is refined, many by-products are produced, one among them is sulphur.
Therefore, statements 2 and 3 are correct. So, the correct option is "2 and 3 only". Hence, the answer provided is accurate.
