The correct answer is D) flash point range and Reid vapor pressure index of petroleum products.
The designations A, B, C, D, and E grades of cargo refer to the flash point range and Reid vapor pressure index of petroleum products. These grades are used to classify the hazards associated with the transportation and handling of different petroleum products based on their flammability and volatility. The flash point and Reid vapor pressure are key parameters that determine the appropriate safety precautions and regulatory requirements for the cargo.
