Solution
The example of a chemical change among the options given is A. Sugar breaking down into water and carbon when it is heated. This is because a chemical change involves a chemical reaction, with new substances produced as a result of the change. In this case, the sugar (sucrose) breaks down into water (H2O) and carbon (C) - different substances from the original sugar. The other options (B, C, and D) are examples of physical changes, where no new substances are produced.
