Which statement best describes the difference between AVGAS and jet fuel?

Explanation:
The main idea is that engine type drives the fuel choice. AVGAS is gasoline designed for piston (reciprocating) aircraft engines and uses high octane to prevent knocking in spark-ignited systems. Jet fuel, by contrast, is kerosene-based and used in turbine engines; it includes kerosene grades and blends rather than octane ratings. So the statement that captures this difference—that AVGAS powers reciprocating engines and has high octane, while jet fuel consists of kerosene grades and blends—is the best description.
