D. cannot be reversed and can be reversed, respectively.

Answer :

When a chapatti is rolled from a dough, only it’s shape changes from spherical to a flat round one. There is no change in its chemical properties and hence, the change can be reversed.

When a chapatti is baked, heat brings about chemical changes in its properties. Therefore, baking of chapatti is a change which cannot be reversed.
