If they were pulling the box instead of pushing it up .

Option (c) is correct. Biofuel is the alternative energy technology which is most likely to be used to power a car.

Further Explanation:

In the current time, there are several alternative sources of energy developed in order to maintain the proper balance in the amount of the non-renewable sources of energy like fossil fuels and natural gas.

The various energy technologies that are widely used as the alternative sources of energy in the various fields are the wind energy, hydropower, biofuel, geothermal energy etc.

In order to power a car by means of an alternative energy technology, the wind energy and the hydro energy are possibly not the appropriate form as they are produced in the very huge power plants and in the large tidal farms. Therefore, these forms of energy cannot be used.

The geothermal energy coming from beneath the earth can also not be harnessed by the car to obtain power from it. Therefore, the biofuel is the easiest energy technology as it can be easily used in a car. The biofuel is produced by using the small and portable energy production unit.

Thus, Option (c) is correct. Biofuel is the alternative energy technology which is most likely to be used to power a car.
