D 7'06"
AI Explanation

The correct answer is B) 8'06". The mean draft is calculated by taking the average of the forward and aft draft marks. In this case, the forward draft is at the top of the 8, which indicates 8 feet, and the aft draft is also at the top of the 8, which also indicates 8 feet. Therefore, the mean draft is the average of these two measurements, which is 8 feet and 6 inches (8'06"). The other answer choices are incorrect because they do not accurately represent the average of the forward and aft draft marks provided in the illustration.
