The correct options are
A Old and inefficient methods of production.
C Varying Sucrose content
D Seasonal nature of Sugarcane
Sugar mills in India have been shifting to southern and western states due to the higher sucrose content in the sugarcane produced in these regions. Apart from seasonal nature, the sugar industry also face other challenges such as old and inefficient methods of production, and lack of efficient transportation. Another challenge of the industry is that it is still not able to fully utilise the potential of bagasse usage.
