I think the correct answer from the choices listed above is option C. It is weathering that  produces the sediments that ultimately lead to soil formation. Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, waters, and biological organisms.
