Concept:LPG (liquefied petroleum gas) is a mixture of propane and butane, not methane. Methane is the main component of natural gas, not LPG.
Explanation:LPG is a clean fuel because it burns almost completely without leaving soot or smoke.
It has a high calorific value, meaning it releases a lot of heat per unit mass.
When burning, LPG produces a clear blue flame indicating complete combustion.
LPG is made up of hydrocarbons like propane and butane, not methane.
Methane is the primary gas in natural gas (CNG), not in LPG.
Hence, the statement “It is methane emitting” is false for LPG.
Answer:It is methane emitting (Option D)
