A 1.96 feet
B 2.28 feet
C 2.65 feet
D 2.93 feet
AI Explanation

The correct answer is B) 2.28 feet. The reasoning is based on the stability requirements for vessels, specifically the formula for the maximum allowable vertical center of gravity (VCG) for a given combination of below-deck tonnage and above-deck cargo. The formula is: Max VCG = (400 tons x 0 feet + 225 tons x 3.4 feet) / (400 tons + 225 tons), which simplifies to 2.28 feet. The other options are incorrect because they do not properly apply the formula for calculating the maximum allowable VCG given the provided information. Option A is too low, Option C is too high, and Option D is also too high.
