Concept:Burning fossil fuels releases greenhouse gases such as carbon dioxide (
CO2), which trap heat in the atmosphere.
Explanation:Natural gas is a fossil fuel mainly made of methane (
CH4).
When it burns, it produces carbon dioxide (
CO2), a major greenhouse gas.
Nuclear, wind, and solar energy sources do not release significant greenhouse gases during power generation.
Therefore, among the given options, natural gas contributes to the greenhouse effect.
Answer:A. Natural gas
