What does CNG stand for?

The term CNG stands for Compressed Natural Gas, which is a type of fuel that is used primarily in vehicles and for heating purposes. Compressed Natural Gas is composed mainly of methane and is favored for its cleaner-burning properties compared to traditional gasoline or diesel fuels. It is stored at high pressure, making it efficient for transportation and storage.

Choosing Compressed Natural Gas is accurate because it reflects the widespread usage and recognition of this energy source in the context of energy production, vehicle fuel, and environmental considerations. The other options present gases that are either not utilized in similar applications or refer to concepts that are not relevant to the context of fuel types. For instance, Compressed Nitrogen Gas and Compressed Neon Gas do not serve as fuel sources and Circuit Neutral Ground is a term that relates to electrical grounding concepts, not gases. This specificity is crucial for understanding the significance and application of CNG in various industries.
