Class II liquids are indeed categorized as combustible liquids, which means they have a flash point between 100°F (37.8°C) and 140°F (60°C). This classification is based on the behavior of these liquids under certain temperatures and conditions. When a liquid falls into the Class II category, it indicates that it can ignite and burn if exposed to an open flame or high enough temperatures, but it does not ignite as easily as flammable liquids (which have lower flash points).

Understanding combustible liquids is crucial for workplace and environmental safety because they require specific handling and storage measures to prevent accidental ignition and fire hazards. Proper training in recognizing the properties of these liquids helps ensure a safer environment and informs safety protocols and emergency response procedures.

Other choices do not accurately represent the definition of Class II liquids. For instance, Class II liquids are considered combustible without needing to be heated or mixed with other substances. Additionally, statements implying conditional classifications, such as only being combustible when heated or mixed, misinterpret the inherent properties of Class II liquids.
