Solution

The correct option is A

Chemical


When you take some chapatti dough and roll it out, you are just changing the shape of the dough. Can you reshape the rolled dough to how it was before? Of course! Whenever we are just changing the shape or the state of something and not creating a new substance, it's a physical change.

But if you take the same dough and cook it on a pan to make a chapatti, it's a chemical change. A chapatti is quite different from the dough! Think about it. can you take the chapatti and make dough out of it? Nope. It's a chemical change.
