A 1.17 foot
B 1.30 feet
C 0.91 foot
D 1.06 foot
AI Explanation

The correct answer is B) 1.30 feet. 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 effect of the liquids in the tanks, which can affect the vessel's stability. Using the white pages and the given drafts of 11'-01" forward and 14'-07" aft, we can find the corresponding free surface correction of 1.30 feet. The other answer choices are incorrect because they do not match the value provided in the reference book for the given conditions.
