According to U.S. regulations, which grade(s) of cargo may be carried in tanks that are vented only with gooseneck vents and flame screens?
AI Explanation
The correct answer is A) D or E.
According to U.S. regulations, cargo grades D and E may be carried in tanks that are vented only with gooseneck vents and flame screens. These lower-grade cargoes have lower vapor pressure and are less hazardous, so they do not require the more stringent venting requirements of higher-grade cargoes like B or C.
The other options are incorrect because B or C cargoes would require more sophisticated venting systems beyond just gooseneck vents and flame screens, while option C, B only, is too restrictive and does not align with the regulations.
