The correct answer is (d) Rocky River Stage

Explanation: In this type of stage of the river the flow is formed by rapid erosion. These river reaches have high steep with swift flow, and form rapids along their courses. The bed load carried by these reaches cannot be determined by usual bed load transportation formulas.
