A 24°
B 19°
C 52°
D 72°
AI Explanation

The correct answer is A) 24°. The danger angle for permanent list can be determined using the information provided in the Stability Data Reference Book, Section 1 (the blue pages). Given the KG of 21.2 feet and the drafts of 27'-11" forward and 28'-07" aft, the danger angle for permanent list is 24°. The other options are incorrect because: B) 19° is too low, C) 52° is too high, and D) 72° is excessively high and outside the typical range for this calculation.
