Question 4290 Deck General

The correct answer is C) 13.0 seconds. The reasoning is based on the relationship between the roll period and the water depth. In deeper water, the roll period of a vessel increases. With a water depth of 200 feet and a roll angle of 2.5 degrees, the roll period should be longer than 13.0 seconds, as per the principles of naval architecture and ship stability. The other options are incorrect because: A) 0.8 second is too short for a vessel in 200 feet of water depth, B) 6.2 seconds is also too short, and D) 17.0 seconds, while a possible answer, is not the most appropriate choice given the provided information.
