Final answer:
The advantage of using nuclear energy over fossil fuels is that more energy can be extracted from a smaller amount of nuclear material, resulting in less environmental impact compared to coal mining and it emits no greenhouse gases during operation.
Step-by-step explanation:
One advantage of using nuclear energy instead of fossil fuels is: C. More energy can be obtained from a given amount of nuclear material. This is because uranium, the fuel used in nuclear power plants, generates an extremely high amount of power per unit weight or volume. In comparison to the extensive landscape damage caused by coal mining, including practices such as mountaintop removal, less uranium needs to be mined, significantly reducing ecological disruptions. Moreover, nuclear power plants generate electricity without emitting harmful air pollutants like those from fossil fuel-fired plants, contributing to a reduction in chronic health issues related to air quality and avoiding the production of carbon dioxide, thus not exacerbating global warming.
