AI Explanation

The correct answer is C) 10'-10". The mean draft is calculated by taking the average of the forward and aft draft readings. In this case, the forward draft is 11 inches minus 4 inches, which is 7 inches. The aft draft is at the top of the 10, which is 10 inches. The average of these two readings is (7 inches + 10 inches) / 2 = 8.5 inches, which equals 10 feet and 10 inches. The other options are incorrect because they do not accurately reflect the average of the forward and aft draft readings provided in the problem statement.
