Answer: C. carbon atoms
Explanation:
Non-renewable energy resources is a term usually used to refer to fossil fuels such as oil, natural gas and coal. These fossil fuels are so termed as they are remains of dead plant and animal matter from millions of years ago.
The main element in these fossil fuels is carbon which is the universal building block of life so will be present in the remains of previously alive matter. When non-renewable energy sources are therefore used, it is energy from carbon atoms that is being harnessed.
