The correct answer is: Both a & b
The Government of Tamil Nadu promotes electric vehicle (EV) adoption to reduce air pollution and lower fuel costs.
Air pollution is a major problem in Tamil Nadu, as it is in many other parts of India. The state government has taken a number of steps to address this issue, including promoting the use of EVs. EVs produce zero emissions, which helps to improve air quality.
Fuel costs are also a major concern for many people in Tamil Nadu. The price of gasoline has been rising steadily in recent years, and this has put a strain on household budgets. EVs are more efficient than gasoline-powered vehicles, which means that they can save drivers money on fuel costs.
In addition to reducing air pollution and lowering fuel costs, EVs also have a number of other benefits. They are quieter than gasoline-powered vehicles, which can help to reduce noise pollution. They are also more reliable and require less maintenance than gasoline-powered vehicles.
The Government of Tamil Nadu is committed to promoting the use of EVs, and it is working to create a more sustainable transportation system for the state.
