Which one of the following is a chemical property of matter?

Combustibility is a chemical property of matter because it describes the ability of a substance to react with oxygen and undergo a chemical change during combustion, resulting in the release of energy in the form of heat and light, along with the production of new substances, such as gases or ash. This characteristic indicates how a substance will behave chemically when exposed to certain conditions, specifically fire or high temperature.

In contrast, the other options—texture, color, and temperature—are physical properties. Texture refers to the surface quality and feel of a material, color pertains to the visual perception of light wavelengths reflected off a substance, and temperature is a measure of the average kinetic energy of the particles in a substance. These physical properties do not involve a change in the chemical structure of the material and do not indicate how a substance will react chemically in different situations. Thus, combustibility stands out as it is directly linked to chemical changes and reactions.
