A It has a Reid vapor pressure of 9.5.
B It has a specific gravity of 1.3.
C The boiling point is 215°F (102°C).
D It is a grade E combustible liquid.
AI Explanation

The correct answer is D) It is a grade E combustible liquid. Castor oil is classified as a grade E combustible liquid under the U.S. Coast Guard regulations. This means it has a flash point at or above 100°F (37.8°C) and below 200°F (93.3°C). The other options provided are incorrect, as they do not accurately describe the properties of castor oil. Specifically, the boiling point of castor oil is higher than 215°F (102°C), and its specific gravity is lower than 1.3.
