The correct answer is coking coal

  • Saltpetre (Potassium nitrate) is not used in the production of Steel.
  • It is used in the production of fertilizers, tree stump removal, rocket propellants and fireworks.
  • It is one of the major constituents of gunpowder (black powder) and has been used since the Middle Ages as a food preservative.
  • Rock phosphate is used in the production of fertilizer and not for the production of Steel. 
  • India imports coking coal. Hence Option 3 is Correct.
  • The production of steel requires 0.8 tonnes of coking coal to produce one tonne of Steel.
