Answer: Option (d) is the correct answer.
Explanation:
A property that does not bring any changes in the chemical composition of a substance is known as a physical property.
For example, hardness, density, boiling point, conductive nature etc are all physical properties.
On the other hand, a property that brings changes in the chemical composition of a substance is known as a chemical property.
For example, reactivity, toxicity etc are all chemical properties.
Thus, we can conclude that ability to combine with hydrogen is not a physical property.
