Expert Solution

Hi there,

Answer: (C) Carbon black forms during the incomplete combustion of hydrocarbons like methane.

Carbon black is produced by the incomplete combustion of a hydrocarbon fuel such as oil or gas, fossil fuels, wood and other fuels with a limited supply of combustion air, Methane is a simplest hydrocarbon and completely combust to give CO₂ & H₂O, but we can manage to get carbon black as it gives finest carbon footprint. Since town gas consist of CO, H₂ and CH₄ from the incomplete combustion of coal. Wood gives first coal not carbon black.

Hope this helped you!

Thank You So Much!
