d) Glass

Answer 2

Answer:

The correct answer is (d) glass.

Explanation:

• Glass is made up of fully oxidized silicon. Glass can be burnt only when high temperature is applied to it which results in the breakdown of the oxygen-silicon bond.
• When subjected to high temperature it may crack or break but doesn't catch fire easily.
• On the other hand LPG, kerosene and even dry grass are highly inflammable and catch fire immediately.
• They have very low ignition temperature.
• Some other non-inflammable substances are: helium, steel, diamond etc.
