The correct answer is C. animal actions.
Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition. One cause of mechanical weathering is animal actions, such as burrowing by animals which can disturb the soil and rocks, leading to fragmentation. This process can expose more surface area to further weathering.
