What is a limitation of CNG compared to gasoline?

Answer: B — CNG storage requires larger tanks

CNG requires larger tanks for storage because the gas must be stored at high pressures to ensure that enough fuel can be carried for practical driving ranges. This is a significant limitation compared to gasoline, which has a higher energy density and can be stored in smaller, more compact tanks. The larger size of CNG tanks can impact the vehicle's design, cargo space, and overall weight distribution, making it less convenient for some applications than traditional gasoline tanks. While CNG has advantages such as being cleaner-burning and potentially more economical, the necessity for larger tanks presents a practical challenge that must be considered in vehicle design and operation.
