A.  deposition

Explanation:

As the river is divided into the top three categories on the basis of the depth of the waters and the level of surfaces the rivers are generally in youthful, mature and old stage cycles. As provided by the Davis and penk model that the river when meandering changes there gradient and profiles and thus form long meandering and curved profile as the load-carrying capacity decreases downwards under the impact of gravity. Hence the rover tends to deposit more and more along the tracks a low featured less topography of the monadnock can be seen.
