Physical Property. I hope this helps you, even though it's over a year later!

Answer 2

The correct option is PHYSICAL PROPERTIES.

Objects usually have two different types of properties, these are physical and chemical properties. Physical properties of objects are those properties that can be observed without changing the identity of the objects. An example of these is density. Chemical properties on the other hands are those properties that can only be observed by changing the identity of the object.
