Which fossil fuel produces the least carbon dioxide A)natural gas B)coal C)nuclear energy D)oil

Among the options given, natural gas (Option A) produces the least carbon dioxide when burned for energy. Natural gas is considered a relatively cleaner-burning fossil fuel compared to coal and oil.

Here's a brief explanation for each option:

A) Natural Gas:

• Natural gas is composed primarily of methane (CH₄). When burned, it produces carbon dioxide (CO₂) and water vapor (H₂O). However, it produces fewer carbon emissions per unit of energy compared to coal and oil.

B) Coal:

• Coal combustion releases a significant amount of carbon dioxide, as well as other pollutants such as sulfur dioxide and nitrogen oxides. It is one of the most carbon-intensive fossil fuels.

C) Nuclear Energy:

• Nuclear energy does not produce carbon dioxide during electricity generation. It relies on nuclear reactions, specifically fission, to generate heat. While it does not contribute to CO₂ emissions during operation, it comes with other challenges and concerns, such as radioactive waste.

D) Oil:

• Burning oil products, such as gasoline and diesel, releases carbon dioxide. While it is more energy-dense than natural gas, it still produces more carbon emissions compared to natural gas.

It's important to note that even though natural gas produces fewer carbon emissions than coal and oil, it is still a fossil fuel and contributes to greenhouse gas emissions. The environmental impact of each energy source should be considered within the context of overall energy policies and efforts to address climate change.
