D

Answer 1

The best answer from the choices provided is:

C. Energy processing from corn biofuels is not energy efficient.

This statement is generally considered true as the process of converting corn into biofuels has been criticized for its energy inefficiency and the resources required for cultivation and processing.

The other statements are less accurate:
- A is false because while many biofuels are renewable, they are not composed of 100% renewable materials.
- B is misleading; while algae has potential as a biofuel source, it is not currently the leading source.
- D is false because there are several sources of biofuels, including sugarcane, soybeans, and other biomass materials.
