Which of the following statements about CNG is true?

Compressed Natural Gas (CNG) is recognized as a viable alternative energy source primarily because it burns more cleanly than many conventional fuels, including gasoline and diesel. One of its main advantages is that it produces significantly lower levels of harmful emissions, such as nitrogen oxides (NOx) and particulate matter, compared to diesel and gasoline engines. This makes CNG an attractive option for reducing air pollution and improving overall environmental quality.

Options that claim CNG has a higher explosion risk than gasoline, cannot be stored effectively, or produces more emissions than diesel do not accurately reflect the characteristics and benefits of CNG. In fact, while CNG is flammable, its storage and handling protocols are well-established, making it safe for widespread use. Thus, choosing CNG aligns with sustainability efforts and advancements in cleaner energy technologies, solidifying its status as a viable alternative energy source.
