The correct answer to the question is option 4: All options are correct. Biomass can be obtained from groundnut shells, sugarcane bagasse, and rice husk in India and elsewhere. Biomass refers to organic materials such as agricultural waste, forest residues, and dedicated energy crops that can be used to produce energy. Groundnut shells, sugarcane bagasse, and rice husk are examples of agricultural waste that can be converted into biomass fuel. Groundnut shells are the outer covering of groundnuts, sugarcane bagasse is the fibrous residue left after extracting juice from sugarcane, and rice husk is the outer covering of rice grains. These materials can be used as a renewable source of energy, providing an alternative to fossil fuels.
