Grade D liquids are those having flash points of _______________.

A 150°F or greater but less than 212°F
B 80°F or less
C 212°F or greater
D greater than 80°F and less than 150°F
AI Explanation

The correct answer is D) greater than 80°F and less than 150°F. According to the regulations governing the US Coast Guard Captain's License Examinations, Grade D liquids are those having flash points greater than 80°F but less than 150°F. This is because liquids in this flash point range are considered moderately flammable and require special handling and storage procedures on vessels. The other options are incorrect because A) 150°F or greater but less than 212°F would be considered Grade C liquids, B) 80°F or less would be Grade B liquids, and C) 212°F or greater would be Grade E liquids, which have different classification and handling requirements.
