Question 1410Navigation General

The correct answer is C) 12 hours. According to standard maritime practices and regulations, it typically takes about 12 hours of steady wind for a wind-driven current to fully develop. This is because it takes time for the wind to transfer its energy to the surface of the water and create a noticeable current. The other answer choices are incorrect because 2 hours is too short for a fully developed wind-driven current, while 6 and 18 hours are not the standard time frame referenced in maritime guidelines.
