Explanation:

the correct answer is "nuclear power plants do not pollute the air". unlike fossil fuel-fired power plants, nuclear power plants do not produce chemicals or other components that could pollute the air. nuclear reactors work with uranium, creating energy by splitting the atoms in a fission chain reaction, which not results in the formation of carbon dioxide or other greenhouse gases.
