Question 503 Deck General

The correct answer is C) a stowage sequence marking. The portion of the symbol indicated by the letter A is a stowage sequence marking, which is used to indicate the order in which packages should be stowed on a vessel. This marking helps ensure proper loading and unloading of cargo, as well as safe stowage during transport. The other options are incorrect because: A) the consignee's marking is typically located elsewhere on the package, B) the symbol for toxic contents would be a different symbol, and D) a stowage mark showing the top of the case would be a different type of marking.
