B 942,120 foot-tons
C 946,271 foot-tons
D 974,441 foot-tons
AI Explanation

The correct answer is B) 942,120 foot-tons. This is the correct answer because the maximum vertical moments, including free surface moments, permitted on the DEEP DRILLER at a draft of 60 feet with winds greater than 70 knots is 942,120 foot-tons, as per the applicable US Coast Guard regulations for offshore drilling units. The other options are incorrect because they do not accurately reflect the maximum vertical moments permitted under these conditions. Option A (1,059,885 foot-tons) is too high, while options C (946,271 foot-tons) and D (974,441 foot-tons) are also inaccurate.
