Answer: Option (c) is the correct answer.
Explanation:
It is known that chemical changes are the changes which tend to show difference in chemical composition of a substance.
For example, toxicity, reactivity, combustion etc are all chemical properties.
When gasoline is burning then a chemical change takes place as combustion is taking place.
A chemical change will always lead to the formation of a new compound and this change is irreversible in nature by any physical means.
On the other hand, a change which is unable to bring any difference in chemical composition of a substance is known as a physical change.
For example, change in shape, size, mass, volume etc are all physical properties.
Breaking glass, melting ice on windshield and denying a bumper are all physical changes.
Thus, we can conclude that out of the given options burning gasoline is an example of chemical change.
