A LCG-FP 268.3 feet
B LCG-FP 272.2 feet
C LCG-FP 265.1 feet
D LCG-FP 263.4 feet
AI Explanation

The correct answer is C) LCG-FP 265.1 feet. To determine the final LCG-FP of the cargo, you need to use the cargo distribution information provided in the table ST-0105 and apply the formula for calculating the LCG-FP. The formula is: LCG-FP = Σ(Weight x Moment) / Σ(Weight). By inputting the weight and moment values from the table, you can calculate the final LCG-FP as 265.1 feet, which matches the correct answer choice C. The other answer choices are incorrect because they do not accurately reflect the final LCG-FP calculated using the provided cargo distribution information.
