\nPropane is an example of a clean fuel among the given options.
\n<\/section>\n
\nClean fuels produce less pollution when burned compared to conventional fuels. Propane, being a gaseous fuel (part of LPG – Liquefied Petroleum Gas), generally burns more cleanly than solid fuels like coke or liquid fuels like petrol and wax, which produce significant amounts of smoke, particulate matter, and other pollutants like sulfur oxides and nitrogen oxides. While no fuel is perfectly “clean,” propane is significantly cleaner than the other options listed in terms of common air pollutants.
\n<\/section>\n
\nCommon examples of cleaner fuels include natural gas (methane), LPG (propane and butane), hydrogen, and biofuels like ethanol and biodiesel (though the ‘cleanliness’ of biofuels is debated depending on production). Coke is a solid fuel derived from coal, primarily carbon, and its combustion produces significant air pollution. Petrol (gasoline) is a complex mix of hydrocarbons used in internal combustion engines and is a major source of air pollution. Wax is a solid hydrocarbon often used in candles or as fuel, producing smoke and particulates when burned.
