Answer: Option (c) is the correct answer.

Explanation:

A property that does not bring any change in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

Water boiling, iodine vaporizing
, and ice melting are all physical changes.

And, a property that changes chemical composition of a substance is known as chemical property.
