B 1.15 feet
C 1.25 feet
D 1.31 feet
AI Explanation

The correct answer is B) 1.15 feet. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book. Based on the given drafts of FWD 15'-05" and AFT 21'-03", we can find the corresponding free surface correction in the reference book. The correct value is 1.15 feet. The other options are incorrect because they do not match the value provided in the reference book for the given drafts. Option A (1.05 feet) and options C (1.25 feet) and D (1.31 feet) are not the correct free surface correction for the provided information.
