Question 953 Deck General

The correct answer is D) D or E. According to regulations, cargo grades D and E are permitted to be carried on a barge in tanks fitted only with gooseneck vents and flame screens. Cargo grades A, B, and C have more stringent requirements for tank ventilation and would not be allowed in tanks with only gooseneck vents and flame screens. Cargo grades D and E have lower flammability and are considered safer to transport in the specified tank configuration. The other options are incorrect because B) B or C would not be permitted, as B is a more hazardous cargo grade, and C) C or D is also incorrect, as C is not allowed in the specified tank configuration.
