Answer is A. We are depleting fossil fuel faster than they form.

Reason: Coal is a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Layers of dirt and rock covered the plants over millions of years.
