B 1.15 feet
C 1.25 feet
D 1.31 feet
AI Explanation

The correct answer is A) 1.05 feet. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book and the given draft and sounding information. The free surface correction depends on the amount of free surface in the tanks, which can be calculated from the tank soundings. Using the provided draft and sounding data, we can look up the free surface correction in the reference book and find that the correct value is 1.05 feet. The other options are incorrect because they do not match the value calculated from the reference book using the given information.
