Which is not a drawback of using fossil fuels? A. They cause air pollution. B. They are nonrenewable. C. They release greenhouse gases. D. They release radioactive waste.

The correct answer is D. They release radioactive waste.<br /><br />Fossil fuels, such as coal, oil, and natural gas, are formed from the remains of ancient plants and animals that have been buried and subjected to high temperatures and pressures over millions of years. When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which contribute to climate change. Additionally, the extraction and transportation of fossil fuels can cause air pollution and environmental degradation.<br /><br />However, the release of radioactive waste is not a drawback associated with the use of fossil fuels. Radioactive waste is typically associated with nuclear power generation, which involves the use of nuclear reactions to generate electricity. Nuclear power plants use uranium, a radioactive element, as fuel, and the process of generating electricity can produce radioactive waste as a byproduct. This waste must be carefully stored and managed to prevent it from contaminating the environment.
