Consider the following statements regarding second-generation (2G) bioethanol and bamboo-based bioenergy: Statement I: Second-generation (2G) bioethanol is produced from non-food biomass such as crop residues and lignocellulosic materials like bamboo. Statement II: 2G bioethanol production relies on simple yeast fermentation of sugar-rich food crops and therefore directly competes with food security. Statement III: Bamboo, being a fast-growing grass with high lignocellulosic content, is suitable as a sustainable biomass feedstock for 2G bioethanol. Which one of the following is correct in respect of the above statements?
