Question 1852Navigation General

The correct answer is C) continue on the present course. When steering on a pair of range lights, if the upper light appears above the lower light, it indicates that the vessel is off the range line and to the right of the intended course. To return to the range line, the vessel should continue on the present course, not come left (A) or come right (D). Waiting until the lights are no longer in a vertical line (B) is also not the correct action, as the vessel should immediately adjust its course to realign with the range lights.
