Choose the correct statement about inflammable substances from the following statements. They have:

A) low ignition temperature and cannot catch fire easily.

B) high ignition temperature and can catch fire easily.

C) low ignition temperature and can catch fire easily.

D) high ignition temperature and cannot catch fire easily.

The correct answer is C) low ignition temperature and can catch fire easily.

• Inflammable substances are materials that can ignite and burn very easily. Examples include petrol, alcohol, and LPG.
• Ignition temperature is the lowest temperature at which a substance will catch fire.

Because inflammable substances require very little heat to start burning, they have a low ignition temperature. This is precisely why they are considered dangerous and can catch fire easily.

Note: The words inflammable and flammable mean the same thing. The opposite is non-flammable.
