  • AThey have a higher energy density per unit volume.
  • BThey are completely carbon-neutral throughout their life cycle.
  • CThey typically produce fewer net greenhouse gas emissions.
  • DTheir production does not require land or water resources.
Explanation

Biofuels, especially from sustainable sources, can result in fewer net greenhouse gas emissions over their life cycle compared to fossil fuels because the CO2 released during combustion is largely offset by the CO2 absorbed during the growth of the biomass.
