Answer & Explanation
The correct answer is Option A: The ignition of a combustible material without initiation by a spark or flame, when the material has been raised to a temperature at which self-sustaining combustion occurs..
Auto-ignition refers to the property of a substance whereby it ignites spontaneously without the requirement of an external ignition source like a spark or flame. This occurs once the material reaches its auto-ignition temperature in the presence of an oxidant.
