What is the difference between combustible and non-combustible materials?

The distinction between combustible and non-combustible materials is primarily based on their ability to ignite and sustain a fire. Combustible materials contain organic substances that can catch fire and continue to burn, meaning they have the potential to produce flames and contribute to a fire's spread. Examples of combustible materials include wood, paper, and fabric.

In contrast, non-combustible materials are those that do not ignite, burn, or contribute to a fire's intensity or duration. Materials such as concrete, metal, and certain types of glass belong to this category. Understanding this difference is crucial in fire safety and prevention efforts, as the presence of combustible materials can significantly increase fire risk, while non-combustible materials can help contain or limit fire spread.

The other options do not accurately convey the fundamental properties that define combustible and non-combustible materials, thus making them less suitable as correct responses.
