A 7 psia and a flash point of 80°F
B above 14 psia
C 9 1/2 psia and a flash point of 95°F
D more than 8 1/2 psia but less than 14 psia and a flash point of 72°F
AI Explanation

The correct answer is D) more than 8 1/2 psia but less than 14 psia and a flash point of 72°F. According to the regulations governing the transportation of hazardous materials, a Grade B product has a Reid vapor pressure above 8 1/2 psia but less than 14 psia, and a flash point below 80°F. This matches the specifications provided in option D. The other options are incorrect because: A) A Reid vapor pressure of 7 psia does not meet the requirements for a Grade B product. B) A Reid vapor pressure above 14 psia would be classified as a Grade A product, not Grade B. C) A Reid vapor pressure of 9 1/2 psia and a flash point of 95°F do not match the requirements for a Grade B product.
