70% to pass

A snag or other underwater obstruction may form a _______________.

A V-shaped ripple with the point of the V pointing downstream
B V-shaped ripple with the point of the V pointing upstream
C small patch of smooth water on a windy day
D smoothing out of the vessel's wake
AI Explanation

The correct answer is B) V-shaped ripple with the point of the V pointing upstream. When a vessel encounters a snag or other underwater obstruction, it creates a V-shaped ripple on the water's surface, with the point of the V pointing upstream. This is due to the flow of water around the obstruction, which creates a disturbance that propagates upstream. The other answer choices do not accurately describe the effect of an underwater obstruction on the water's surface.
