The correct answer will be running the non-polluting cars.
Explanation:
The technology of a car engine is based on the use of fuels like petrol and diesel which on combustion provides energy to cars. These fuels although provide energy to the running car but produces harmful gases in the environment like SO₂, CH₄, CO AND CO₂.
Nowadays attempts have been made by the scientist all over the globe to find the alternative sources to run the vehicle which can help in reducing the pollution like battery electric vehicles, flexible-fuel vehicles, compressed-air vehicles, hydrogen and fuel-cell vehicles and hybrid electric vehicles. These vehicles can help reduce pollution and can be a reliable source to depend upon.
Thus, will be running the non-polluting cars is the correct answer.
Developing non polluting cars by developing and using non polluting fuels
Explanation:
Car is one of the fine invention of human being. However, it is considered as polluting because of the fuels used in it which after burning releases harmful gases and dust in the air.
Now a days emphasis is given on sustainable mode and thus petrol and diesel based cars have been restricted from further usage.
Usage of Clean fuel cars i,e CNG and biofuel cars and electric cars are being encouraged in order to curb the problem of population.
