  3. A light blue square with a dark blue X through the square
  4. The image of a bird in a red octagon

Answer: B. The image of a fish in a white triangle with an X through through the fish

The marine pollutant symbol is a white triangle containing a fish with an X drawn through the fish. The handbook says any bulk package of a marine pollutant must show the Marine Pollutant marking: a white triangle with a fish and an X through the fish. It also says this is a marking, not a placard, and that it must appear on the outside of the vehicle as well as on the package. So the symbol to look for is the fish inside the white triangle with the X crossing the fish.
