Solution

The correct option is C composition
A change in which the physical properties of a substance gets altered, without the formation of a new substance is called a physical change. In the given options, colour, state and size are the properties which can define the physical state of a substance while composition defines its chemical state. So, a physical change does not involve any change in composition.
