The correct option is II and III only because statement I inaccurately represents India's per capita carbon dioxide emissions, which are approximately 1.9 t CO2/capita as of recent data, indicating they are more than 0.5 t CO2/capita. Statement II is accurate as India ranks second in the Asia-Pacific for CO2 emissions from fuel combustion, primarily due to rapid industrialization and energy consumption. Statement III is also correct, as the electricity and heat production sector, heavily reliant on coal, constitutes the largest source of CO2 emissions in India, reflecting the country’s energy profile and economic reliance on fossil fuels. These insights are crucial for understanding India's environmental challenges and its role in global climate change discussions.
