D. Complete combustion of fuel — A gas stove flame burns blue because of complete combustion of fuel. Complete combustion occurs when there's a sufficient supply of oxygen. It produces carbon dioxide (CO2) and water vapor (H2O), releasing maximum heat and leaving no soot. A blue flame is also hotter and cleaner, which is ideal for cooking.
