Breakdown of the Problem

1. Identify the characteristics of fossil fuels.
2. Examine each option presented in the question to determine if it qualifies as a fossil fuel.

Relevant Concepts

1. Fossil Fuels: These are natural substances formed from the remains of dead plants and animals over millions of years. Common types include coal, oil, and natural gas.
2. Other Options: Understanding what nuclear, biomass, and geothermal energy represent to differentiate them from fossil fuels.

Analysis and Detail

1. Option A: Nuclear - This is a form of energy produced through nuclear reactions (fission) and is not derived from organic materials; therefore, it is not a fossil fuel.
2. Option B: Biomass - This includes organic materials that can be used as fuel. While it is renewable and derived from living organisms, it is not classified as a fossil fuel.
3. Option C: Coal - This is a classic example of a fossil fuel, formed from ancient plant matter subjected to heat and pressure over millions of years.
4. Option D: Geothermal - This refers to heat generated from the Earth’s core and is a renewable energy source, not a fossil fuel.

Verify and Summarize

Only coal meets the definition of a fossil fuel as it is formed from ancient organic matter. The other options either come from renewable sources (biomass and geothermal) or involve non-fossil-based energy production (nuclear).

Final Answer

C. Coal
