A LCG-FP 267.12 feet
B LCG-FP 268.48 feet
C LCG-FP 270.97 feet
D LCG-FP 273.06 feet
AI Explanation

The correct answer is C) LCG-FP 270.97 feet. To determine the final LCG-FP of the cargo, we need to use the cargo distribution information provided in the table ST-0194 and apply the calculation formula to find the weighted average LCG-FP. The formula for calculating the weighted average LCG-FP is: (Sum of weight x LCG-FP) / Total weight. By applying this formula to the given cargo distribution, the final LCG-FP of the cargo works out to 270.97 feet, which matches the correct answer C. The other options are incorrect because they do not accurately reflect the final LCG-FP calculated using the provided cargo information and the standard formula.
