The burning of coal, a fossil fuel, produces water and carbon dioxide. How is this similar to cellular respiration?
A) Both require high temperatures.
B) Heat energy is lost in both cases.
C) Both involve the breakdown of carbon compounds.
D) Some amount of carbon remains un-oxidized in both cases.

Answer I did this because you didn't have the right chose

Explanation and who gave you this

They did the answer wrong

The greenhouse-gas problem is relatively easy to grasp. All fossil fuels are made up of mostly carbon and hydrogen. When burned, the carbon is converted to carbon dioxide and the hydrogen to water. Each of those reactions produces a slightly different amount of heat.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
