Thank you, Ms.Sue and Callie for the answers ;).

Yes, the correct answer is C. Plants and animal waste is commonly used to make biomass fuel. To arrive at this answer, one can eliminate the other options (A, B, and D) based on their sources and properties.

A. Coal is a fossil fuel that is formed from the remains of plant materials over millions of years. It is not considered biomass fuel as it is not derived directly from living or recently living organisms.

B. Natural gas is a fossil fuel that is primarily composed of methane. It is also not considered biomass fuel as it is not sourced from plants or animal waste.

D. Petroleum, also known as crude oil, is a fossil fuel that is derived from ancient marine organisms. Like coal and natural gas, petroleum is not classified as biomass fuel.

By process of elimination, we can determine that the correct answer to the question is option C, which states that biomass fuel is made from plants and animal waste.
