Aerosols are the minute particles that are released with the pressure and remain suspended in the air. These can be sold particles or liquid droplets. The natural aerosols appear in the form of the fog, dust, forest exudates, geyser steams etc. The anthropogenic aerosols are more harmful and persist for the longer duration, like smoke, particulate matter etc. The emission from the jets comprises mainly of the fluorocarbons that are emitted with an immense pressure to provide propulsion to the engine.
Hence, the correct answer is 'Fluorocarbon'.
