A 1.20 feet
B 0.61 foot
C 0.92 foot
D 0.73 foot
AI Explanation

The correct answer is D) 0.73 foot. 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 accounts for the effect of liquids sloshing in partially filled tanks, which can adversely impact a vessel's stability. Based on the information provided, the free surface correction is 0.73 foot. The other options are incorrect because they do not accurately reflect the free surface correction calculated using the stability data and the vessel's drafts and soundings.
