Electric cars are not hybrid cars, but to clarify the descriptions provided:
A) They produce more pollutants - False. Electric cars typically produce fewer pollutants than conventional internal combustion engine vehicles, especially when powered by renewable energy sources.
B) They burn more fossil fuels than other cars - False. Electric cars do not burn fossil fuels directly, although the electricity they use may be generated from fossil fuel sources. However, they are generally more efficient than traditional gas-powered vehicles.
C) They are fuel efficient - True. Electric cars are generally considered more fuel-efficient because they convert a higher percentage of electric energy from the grid to power at the wheels compared to internal combustion engines.
D) They run fully on unlimited resource - Partially true. Electric cars can be powered by renewable energy sources (like solar, wind, and hydro), which are more sustainable compared to fossil fuels. However, no resource is unlimited in the strictest sense.
So, the best description from the given options is C: they are fuel efficient.
