A 0.91 foot
B 1.30 feet
C 1.17 foot
D 1.01 foot
AI Explanation

The correct answer is D) 1.01 foot. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book and the given tank sounding information. Based on the drafts provided (FWD 13'-10", AFT 16'-04"), we can find the corresponding free surface correction of 1.01 foot from the tables in the reference book. The other answer choices are incorrect because they do not match the free surface correction value determined from the reference material and the provided tank sounding data.
