Explanation:

Chemical weathering involves chemical reactions that change the composition of rocks. Option A is human - induced mechanical breaking, Option B is physical weathering (freeze - thaw action), Option D is human - made mechanical alteration. Option C: Acid rain (containing acidic substances) reacts with granite, changing its minerals (chemical change), so it's chemical weathering.
