Identify the wrong pair

A. Deposition - V–shaped valley


B. Transport - Ripple Marks

A

B is Correct because the ripple marks are formed when water flows or wind blows over the loose sand and the sand towards the bottom is pulled or pushed in the direction of flow.


C is Correct because Mushroom rocks are those rocks where the landform are formed due to erosional work of wind.
