Answer 2

C. asbestos

Explanation:

A non- combustible material is a substance that will not ignite, burn, support combustion. It does not release flammable vapors when subject to fire or heat, in the form in which it is used and under conditions anticipated.  

Asbestos works well as a fire-resistant material because of its chemical properties. It is non-flammable and non-combustible and has a melting point of around 1600 degrees Fahrenheit.

Option C is the answer.
