Answer:
B
Explanation:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
Malleability, Solubility, and Density are all characteristics that can be observed without changing the identity of the substance. Combustibility, on the other hand, refers to the tendency of a substance to burn as a result of fire or chemical reaction. This means it is a chemical property, because it describes the ability for a substance to undergo a specific chemical change.
