Answer:
Coal
Explanation:
Ignition temperature is the temperature at which a substance starts burning. Coal requires a very high initial temperature to start burning. Different combustible substances catch fire at different temperatures. A combustible substance cannot catch fire or burn if its temperature is lower than its ignition temperature.
Due to the highest carbon content and fewest impurities, anthracite is the highest grade of coal, whose surface is shining and has the highest calorific value.
