Which describes electric cars or hybrid cars?

A. they burn more fossil fuels than other cars.
B. they are fuel-efficient
C. they produce more pollutants.
D. they run fully on unlimited resources.

B. they are fuel-efficient

B. they are fuel-efficient

To determine which option accurately describes electric cars or hybrid cars, we need to consider some basic knowledge about these vehicle types.

Electric cars: These vehicles run solely on electricity and are powered by rechargeable batteries. They do not rely on fossil fuels, such as gasoline or diesel, for propulsion.

Hybrid cars: These vehicles combine the use of an internal combustion engine (usually gasoline-powered) with an electric motor. They have both an electric drive system and a conventional engine, which work together to optimize fuel efficiency.

Now, let's analyze each option:

A. Electric cars and hybrid cars do not burn more fossil fuels than other cars. In fact, they rely less or entirely on electricity, which is generated from various sources such as renewable energy (solar, wind, hydro) or from a power grid. Therefore, option A is incorrect.

B. Both electric cars and hybrid cars are known for being fuel-efficient. Their main advantage is reducing fuel consumption and minimizing greenhouse gas emissions compared to traditional gasoline or diesel-powered vehicles. This makes option B the correct answer.

C. Electric cars and hybrid cars do not produce more pollutants. In fact, they produce fewer emissions compared to conventional internal combustion engine vehicles because they rely on electric power, which results in lower or zero tailpipe emissions. This makes option C incorrect.

D. Electric cars partially rely on limited resources (the availability of electricity), while hybrid cars also depend on gasoline or diesel fuel. Hence, they do not run fully on unlimited resources. So, option D is incorrect.

To summarize, the correct option that describes electric cars and hybrid cars is:

B. They are fuel-efficient.
