Gasoline is known for its high volatility, which means it evaporates quickly and produces flammable vapors at normal temperatures. These vapors can ignite easily when exposed to an ignition source, posing a significant combustion risk. The physical properties of gasoline, including its low flash point (the temperature at which it can form an ignitable mixture in air), contribute to this risk.

In contrast, vegetable oil and mineral oil have higher flash points and are generally less volatile, making them less prone to ignition under standard conditions. Water, being a non-flammable liquid, does not pose any combustion risk at all. Therefore, gasoline stands out as the liquid most likely to pose a combustion risk due to its volatility and the nature of its vapors.
