Which is an example of a grade B flammable liquid?

A Phenol
B Allyl alcohol
C Acetaldehyde
D Carbon disulfide
AI Explanation

The correct answer is D) Carbon disulfide. Carbon disulfide is a grade B flammable liquid according to the U.S. Coast Guard regulations. Grade B flammable liquids have a flash point below 80°F (26.7°C) and a boiling point at or above 100°F (37.8°C). Carbon disulfide meets these criteria, as it has a flash point of -22°F (-30°C) and a boiling point of 115°F (46.1°C). The other options are incorrect because: A) Phenol is not a flammable liquid, B) Allyl alcohol is a grade C flammable liquid, and C) Acetaldehyde is a grade A flammable liquid.
