A fossil fuel from plants that lived millions of years ago.

• A. Coal
• B. Nuclear Power
• C. Biomass Energy
• D. Geothermal Energy

Answer: (A)

Fossil fuels come from organic material that lived long ago and was transformed by heat and pressure over millions of years. Coal fits this idea perfectly because it forms from ancient plants that grew in swampy areas, were buried, and, under geological heat and pressure, transformed into a dense, carbon-rich rock. That long process of transformation is what makes coal a fossil fuel derived from ancient plant matter.

Nuclear power, on the other hand, relies on splitting atoms and is not tied to ancient plant matter. Biomass energy uses living or recently living organic material, such as wood or crop waste, not material that has fossilized over millions of years. Geothermal energy comes from heat inside the Earth, not from plant remains.
