Answer: (A)

Verified step by step guidance

1. Understand the term 'fossil fuels': Fossil fuels are natural energy sources such as coal, oil, and natural gas that are derived from the remains of ancient plants and animals.
2. Recognize the process of formation: Over millions of years, the remains of these organisms were buried under layers of sediment and subjected to heat and pressure, transforming them into fossil fuels.
3. Eliminate incorrect options: Fossil fuels are not produced by living organisms in present-day ecosystems, nor are they created by the direct fossilization of minerals. Additionally, they are not exclusively found in areas with abundant dinosaur fossils.
4. Identify the correct reasoning: The term 'fossil' in fossil fuels refers to their origin from ancient biological material that has undergone geological processes over time.
5. Conclude: The correct answer is that fossil fuels are formed from the remains of ancient plants and animals buried and transformed over millions of years.
