Final answer:
Nuclear fission is favorable for producing minimal air pollution compared to fossil fuels but generates radioactive waste that must be safely managed and stored.
Step-by-step explanation:
The correct statement about nuclear fission is that it gives off less air pollution than fossil fuels but does produce radioactive waste. Nuclear power plants generate clean electricity by using fission, which does not emit the air pollutants commonly associated with the combustion of fossil fuels, nor does it produce carbon dioxide during operation, making it an environmentally friendly alternative in terms of air quality and greenhouse gas emissions. However, a significant concern with nuclear fission is that it results in radioactive waste, which poses storage and environmental contamination challenges.
