Answer : 4. "Nagpur"
Explanation :

Answer: D) Nagpur Explanation: With India's pledge to go all electric by 2030, Nagpur will be the first city in the country to adopt electric cabs as the country moves a step closer to its goal. The pilot project will see around 200 e-cabs in Nagpur with the local body to provide for the charging stations across the city. Currently, Mahindra and Honda are few of the car-manufacturers who have electric and hybrid vehicles in their line-up. We do hope that the situation changes, as hybrid and electric vehicles will help in the growing pollution in India. Countries such as France, Netherland and Belgium have already started to adopt electric and hybrid vehicles.
