B Butadiene

AI Explanation

The correct answer is A) Carbon Disulfide. Carbon Disulfide is classified as a Grade B flammable liquid according to the US Coast Guard regulations. Grade B flammable liquids have a flash point below 80 degrees Fahrenheit and a boiling point at or above 100 degrees Fahrenheit. Carbon Disulfide meets these criteria, with a flash point of -22°F and a boiling point of 115°F. The other options are incorrect because: B) Butadiene is a Grade A flammable gas, C) Carbon Tetrachloride is a non-flammable liquid, and D) Ethyl Chloride is a Grade D flammable liquid.
