Which of the following fuel types is specifically designated as Jet A?

Jet A is a specific type of aviation turbine fuel that is used predominantly in commercial jet engines. It is characterized by its distinct properties, including a high flash point and low viscosity, which make it suitable for high-performance aircraft. Jet A is refined from crude oil and blended with certain additives to ensure it meets the required performance standards for safe and efficient operation of jet engines.

In contrast, aviation gasoline is used primarily for piston-engine aircraft, while sustainable aviation fuel is an alternative that can be derived from various sustainable sources and designed to reduce carbon emissions. "Dinosaur fuel" is a colloquial and non-scientific term often referring to fossil fuels, which do not specifically align with the refined specifications of Jet A. Therefore, the designation of Jet A specifically applies to the type of jet fuel that meets established industry guidelines for turbine engines.
