macroscopic property

Explanation:

A macroscopic property is a characteristic of a substance that can be observed with the naked eye. Color change during a chemical reaction is visible without the need for microscopic equipment, so it is a macroscopic property. Microscopic properties involve the behavior of individual atoms or molecules and are not directly observable with the naked - eye. A system boundary is a physical or conceptual separation between a system and its surroundings, and potential energy change is related to the stored energy in a system due to its position or state, neither of which is related to color change in this context.

Answer:

c) Macroscopic property
