  1. 1.Bagasse can be used as biomass fuel for the generation of energy.
  2. 2.Molasses can be used as one of the feedstocks for the production of synthetic chemical fertilisers.
  3. 3.Molasses can be used for the production of ethanol.

Select the correct answer using the code given below:

  1. A.1 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
▶ Answer & Explanation

Correct answer: C. 1 and 3 only

Bagasse, the fibrous residue left after crushing sugarcane, is a significant source of biomass energy and is widely used in sugar mills to generate steam and electricity. Molasses, a viscous syrup produced during sugar refining, is a primary feedstock for the production of ethanol through fermentation. While molasses can be used in animal feed and for producing certain industrial chemicals, its direct use as a feedstock for synthetic chemical fertilizers is not a common or primary application.
