Answer: Option (c) is the correct answer.

Step-by-step 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.
