Answer: Option (d) is the correct answer.
Explanation:
Properties that are unable to bring any change in chemical composition of a substance are known as physical properties.
For example, size, shape, volume, density, boiling point, melting point etc is a physical property.
Whereas properties that bring change in chemical composition of a substance are known as chemical properties.
For example, combustion, toxicity, reactivity etc are all chemical properties.
Thus, we can conclude that a physical property is a property the sample displays without changing its composition.
