b) Carbon dioxide is used in fire extinguisher.
c) C.N.G (compressed natural gas) is a cleaner fuel because it causes less pollution by emitting fewer pollutants like carbon dioxide, carbon monoxide, sulphur dioxide, nitrogen dioxide, particulate matter, unburned hydrocarbons etc.
d) Natural gas produces far fewer harmful emissions and hydrocarbons than gasoline. Using CNG makes the engine cleaner and more efficient. Unlike gasoline, CNG minimizes harmful carbon deposits when combusted. This results to a cleaner and more efficient engine as well as longer lasting spark plugs.
