Major contributor to carbon monoxide emissions in metropolitan areas of India is/are:
Transport Sector
The question asks about the major contributor to carbon monoxide emissions in metropolitan areas of India. Let's analyze the options to determine the correct answer.
- Industrial Sector: Factories and industrial facilities contribute to air pollution, but they are more associated with sulfur dioxide (SO2) and oxide of nitrogen (NOx) emissions rather than carbon monoxide.
- Domestic Sources: Domestic activities such as cooking and heating can produce carbon monoxide but on a much smaller scale compared to urban vehicular emissions.
- Transport Sector: The transport sector, particularly road vehicles using gasoline and diesel, is regarded as one of the largest contributors to carbon monoxide (CO) emissions. The combustion engines produce CO due to incomplete combustion of carbon in fuels.
- Agriculture Sector: Generally not a significant source of carbon monoxide emissions. Agricultural activities mainly release methane (CH4) and ammonia (NH3).
From the above analysis, it is clear that the Transport Sector is the major contributor to carbon monoxide emissions in metropolitan areas of India. This is because vehicles are in continuous operation in these urban areas, leading to a significant amount of carbon monoxide being released into the atmosphere due to incomplete fuel combustion.
Conclusion: The correct answer is Transport Sector as it is the largest source of carbon monoxide emissions in metropolitan areas.
