Answer:

D. Change in shape

Explanation:

Change in shape is the physical property of the substance. Chemical change of the compound is observed during a chemical reaction. Change in colour, production of the gas, formation of a precipitate are the examples of chemical change and can be sensed easily.

Vapour pressure, boiling point, density and shape are the examples of physical properties of compounds. Chemical change also leads to change in texture of the compound. A compound has both physical and chemical properties and its chemical reaction is enhanced by the catalyst.
