What is classified as a combustible liquid?

A Carbon tetrachloride
B Ethyl alcohol
C Tetraethylene glycol
D Acetaldehyde
AI Explanation

The correct answer is C) Tetraethylene glycol. Combustible liquids are defined as liquids with a flashpoint at or above 100°F (37.8°C) and below 200°F (93.3°C). Tetraethylene glycol, a colorless, viscous liquid, has a flashpoint above 200°F, making it a combustible liquid. The other options - carbon tetrachloride, ethyl alcohol, and acetaldehyde - are either not liquids or have flashpoints below 100°F, classifying them as flammable rather than combustible liquids.
