Which term is best described as the property that indicates whether a substance can burn?

• A. pH
• B. Chemical property
• C. Combustibility
• D. Reactivity

Answer: (C)

Combustibility is the property that indicates whether a substance can burn. It’s a specific chemical property that describes a material’s potential to undergo combustion when exposed to heat and oxygen. The other terms don’t fit as neatly: pH measures acidity or basicity, not burning. A chemical property is a broad category that includes combustibility, but it’s not as precise. Reactivity describes how a substance interacts with other substances, which can include burning but isn’t the direct descriptor of burning potential. So combustibility is the best term.
