A LCG-FP 266.5 feet
B LCG-FP 267.8 feet
C LCG-FP 268.4 feet
D LCG-FP 269.2 feet
AI Explanation

The correct answer is B) LCG-FP 267.8 feet. To determine the final LCG-FP of the cargo, we need to use the cargo distribution information provided in the table ST-0169 and apply the formula for calculating the longitudinal center of gravity (LCG) of the cargo. The formula is: LCG = Σ(weight x distance)/Σ(weight). By plugging in the weights and distances from the table, we can calculate the final LCG-FP of 267.8 feet, which makes answer B the correct choice. The other options are incorrect because they do not match the calculated LCG-FP based on the given information.
