D LCG-FP 256.9 feet
AI Explanation

The correct answer is A) LCG-FP 268.3 feet. To determine the final LCG-FP of the cargo, we need to use the given information about the cargo distribution from the table ST-0107 and apply the calculation for the weighted average of the LCG-FP. The formula for the weighted average LCG-FP is: LCG-FP = (Weight 1 x LCG-FP 1 + Weight 2 x LCG-FP 2 + ... + Weight n x LCG-FP n) / (Weight 1 + Weight 2 + ... + Weight n) Using the information provided, the calculation results in an LCG-FP of 268.3 feet, which is the correct answer. The other options are incorrect because they do not match the calculated result based on the given cargo distribution and weights.
