What is a potential disadvantage of CNG fuel?

Answer: B — Less availability of fueling infrastructure

The choice indicating that a potential disadvantage of CNG fuel is the less availability of fueling infrastructure is accurate because the network of CNG fueling stations is less developed compared to traditional gasoline and diesel stations. This limited availability can pose challenges for drivers, especially on long trips or in areas where CNG infrastructure has not been established. Without adequate fueling stations, drivers may find it difficult to refuel their vehicles, which can lead to concerns about range and convenience. While it is true that CNG may sometimes have a higher initial cost or face emissions concerns, the primary issue affecting widespread adoption and use is the accessibility of fueling options. Limited vehicle options may also be a concern; however, the main challenge remains centered around the infrastructure needed to support CNG vehicles on a daily basis.
