Solution
The correct option is D Adding acid to sugar
Burning of paper and adding acid to sugar are chemical changes. Dissolving sugar in water just makes the sugar molecules stay in between water molecules so no new substance is formed.Tearing of paper just changes the shape and size of the paper and no new substance is formed.
On burning a paper, a new substance (ash) is formed, so,it is a chemical change and also in adding acid to sugar, charring occurs which is also a chemical change.
