Option I (Ethanol) is correct. Ethanol can be produced indirectly through coal gasification. The synthesis gas (CO + H₂) obtained from coal gasification can be catalytically converted into ethanol. Hence, ethanol is a valid output from this process. Option II (Nitroglycerine) is not correct. Nitroglycerine is synthesized using glycerol and nitric acid. Glycerol is derived from biological sources like fats and oils, not from coal or its derivatives. Coal gasification does not contribute to its production. Option III (Urea) is correct. Coal gasification produces synthesis gas, which is used to produce ammonia (via the Haber-Bosch process). Ammonia is then reacted with CO₂ to form urea. Thus, coal gasification is an important step in the production of urea.
