A 0.54 ft
B 0.62 ft
C 0.80 ft
D 0.85 ft
AI Explanation

The correct answer is A) 0.54 ft. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book and the given drafts and tank soundings. Based on the drafts of FWD 21'-04" and AFT 26'-04", we can interpolate the free surface correction from the tables in the reference book. The free surface correction for these drafts is 0.54 ft, which makes option A the correct answer. The other options are incorrect because they do not match the value obtained from the reference book for the given drafts and tank soundings.
