D D
AI Explanation

The correct answer is C) C. According to the regulations, a flammable liquid having a Reid vapor pressure of 8½ P.S.I.A. or less and a flash point of 80°F or below is classified as a Grade C liquid. This is because Grade C liquids have a flash point of 80°F or below, which makes them highly flammable and potentially hazardous. The other answer choices are incorrect because Grade A liquids have a flash point above 80°F, Grade B liquids have a flash point above 80°F but a Reid vapor pressure above 8½ P.S.I.A., and Grade D liquids are used for special purposes and do not meet the criteria for Grade C.
