A LCG-FP 263.8 feet
B LCG-FP 266.5 feet
C LCG-FP 272.6 feet
D LCG-FP 269.8 feet
AI Explanation

The correct answer is D) LCG-FP 269.8 feet. To determine the final LCG-FP of the cargo, you need to use the weight and longitudinal center of gravity (LCG) values provided in the ST-0101 table and calculate the weighted average LCG. This is done by multiplying the weight of each cargo item by its LCG, summing the products, and dividing by the total weight of the cargo. This calculation results in an LCG-FP of 269.8 feet, which is the correct answer. The other options are incorrect because they do not represent the proper weighted average calculation based on the given cargo information.
