Question 1368 Deck General

The correct answer is B) greater than 80°F and less than 150°F. According to the regulations for the US Coast Guard Captain's License Examinations, a Grade D liquid has a flash point greater than 80°F and less than 150°F. This means the liquid will ignite at a temperature above 80°F but below 150°F. The other options are incorrect because A) 212°F or greater is a higher flash point than a Grade D liquid, C) 150°F or greater but less than 212°F is outside the defined range for a Grade D liquid, and D) 80°F or less is a lower flash point than a Grade D liquid.
