Question 2393 Deck Safety

The correct answer is A) 90 tons. Based on the given information, you have 420 tons of below deck tonnage and 150 tons of above deck cargo on board. You must load an additional 135 tons of liquid mud below deck. The remaining deck cargo capacity is the difference between the maximum allowed deck cargo (750 tons) and the total cargo already loaded (420 tons below deck + 150 tons above deck + 135 tons of liquid mud below deck), which equals 90 tons. The other options are incorrect because they do not accurately calculate the remaining deck cargo capacity based on the given information and regulations.
