With reference to chemical fertilizers in India, consider the following statements

At present, the retail price of chemical fertilizers is market-driven and not administered by the Government.
Ammonia, which is an input of urea, is produced from natural gas.
Sulphur, which is a raw material for phosphoric acid fertilizer, is a by-product of oil refineries.

Select the correct statement.

1&2 only

2&3 only

1&3 only

All of the above

Explanation:

Only statements 2&3 are correct.

The Union Government subsidies the urea manufacturing units for the cost of transportation to facilitate the availability of urea at the same maximum retail price all over the country. Also, the Government is subsidizing fertilizers for their availability at reasonable prices for agricultural purposes.
Urea (NH2CONH2) is produced from ammonia (NH3) and gaseous carbon dioxide (CO2) at high pressure and relatively high temperature.
Sulphur is a by-product of processing natural gas and refining high-sulphur crude oils. Even if they use low sulphur crude oil, there is still sulphur emission.
The primary sources of sulfuric acid emissions are combustion of coal, and the industries that manufacture or use it in production, including metal smelters, phosphate fertilizer producers, oil refineries, the chemical industry, battery manufacturers, manufacturers of fabricated metal products, manufacturers of electronic components, and manufacturers of measuring and controlling devices.

Hence option 2nd is correct.
