The correct answer is: A) LPG and Biogas.
LPG (liquefied petroleum gas) and biogas are both clean-burning alternatives to fuelwood. They produce fewer emissions than fuelwood, which helps to improve air quality. They are also more efficient than fuelwood, which means that they can provide the same amount of heat with less fuel. Additionally, LPG and biogas are both renewable energy sources, which means that they do not contribute to climate change.
Coal and kerosene are both fossil fuels, which means that they are non-renewable and contribute to climate change. Deforestation is the clearing of forests, which can lead to a number of environmental problems, including soil erosion, loss of biodiversity, and climate change.
Therefore, the government encourages the use of LPG and biogas as fuelwood alternatives because they are clean-burning, efficient, renewable, and do not contribute to climate change.
