What is the minimum temperature to which a fuel must be heated so that it may catch fire and start burning?

Correct option is C

The correct answer is (c) Ignition temperature.
· Ignition temperature is the minimum temperature to which a fuel must be heated in order for it to catch fire and start burning.
· Different fuels have different ignition temperatures, and they will not burn until they reach this temperature. This is an important concept in fire safety and combustion processes.

· Refers to room temperature, typically around 20-25°C, but not related to the point where substances ignite.
Boiling temperature:
· The temperature at which a liquid turns into vapor but has no direct relevance to ignition or combustion.
