Solution

The correct option is B Charcoal, gas and oil
A thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogen) is called as pyrolysis. It involves the simultaneous change of chemical composition and physical phase. It is an irreversible process. The process is used heavily in the chemical industry to produce charcoal, activated carbon, methanol, and other chemicals from wood, to convert ethylene dichloride into vinyl chloride to make PVC, to produce coke from coal, to convert biomass into syngas and biochar, to turn waste into safely disposable substances, and for transforming medium-weight hydrocarbons from oil into lighter ones like gasoline.
