The correct answer is option C, abrasion
Reason -
Abrasion is a mechanical weathering or scrapping process in which a big rock is broken into smaller rocks when the rock grinds against another rocks or sediment. It usually occurs due to the friction between the rocks when they are carried by wind, waves, water or any other natural or artificial force. While in other processes i.e solution, carbonation and hydration some form of chemical reaction takes place to break the rock.
