C Correct answer
Explanation

Erosion is the geological process in which earth materials are worn away and transported by natural forces such as wind, water, ice, or gravity. In contrast, weathering is the static breaking down of rocks, while oxidation is a specific chemical reaction. Because the question specifies the removal and transport of particles, erosion is the correct term.
