physical property
D
chemical property
Explanation: 

Detailed explanation-1: -A physical property is a characteristic that can be observed or measured without changing the composition of the sample. Physical properties can be used to describe mixtures as well as pure substances.

Detailed explanation-2: -Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

Detailed explanation-3: -The mechanical and physical properties of materials are determined by their chemical composition and their internal structure, like grain size or crystal structure. Mechanical properties may be greatly affected by processing due to the rearrangement of the internal structure.
