Which energy source is associated with natural gas and crude oil formation from ancient organisms?

• A. Nuclear Power
• B. Oil and Gas
• C. Wind Energy
• D. Solar Energy

Answer: (B)

Fossil fuels form from ancient organisms buried in sediments and transformed by heat and pressure over long geological time. Natural gas and crude oil are classic examples of these fuels. The energy source linked to their formation is oil and gas, since they originate from organic matter that has been transformed into hydrocarbons deep underground. Other options describe energy sources that don’t come from ancient organisms: nuclear power uses uranium, while wind and solar rely on atmospheric and solar processes rather than fossilized biology.
