AI Explanation

The correct answer is D) Available GM 4.24 ft. To determine the available GM (Metacentric Height), you need to reference the stability data for the given load condition provided in the table ST-0060. Using the white pages of The Stability Data Reference Book, you can look up the stability characteristics for the specified loading condition and find the available GM. The other answer choices are incorrect because they do not match the GM value calculated from the reference data. Options A, B, and C provide GM values that are not the correct value of 4.24 ft for the given loading condition.
