Question 1855 Deck Safety

The correct answer is D. The symbol from which the height of the center of gravity is measured is the baseline, which is represented by the number 2 in the illustration. This is in accordance with the standard conventions used in stability calculations and illustrations for vessel design and analysis. The other options (5, 4, and 3) represent different reference points or symbols in the illustration, but they do not directly indicate the reference from which the center of gravity height is measured.
