A 1.30 feet
B 1.07 foot
C 0.96 foot
D 0.82 foot
AI Explanation

The correct answer is B) 1.07 foot. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book and the given drafts and soundings. The free surface correction is based on the free surface moment, which is calculated from the tank dimensions and fluid densities. Based on the information provided, the free surface moment corresponds to a free surface correction of 1.07 foot. The other options are incorrect because they do not accurately reflect the free surface correction calculated from the given data using the Stability Data Reference Book. The correct answer of 1.07 foot is the value that matches the specific tank dimensions and fluid densities for the scenario described.
