Through weathering and the erosion of rocks and soil, Earth’s landscape can change drastically overtime. As a result, watersheds may disappear if the land making the watershed is worn away, and the water collected is <span>able to flow back into the river, as the area is level with the rest of the land.</span>
Hello There!
Based on my First Aid classes the answer is D. All of the above.

Hope This Helps You!
Good Luck :)
