What are the natural sources of production of Hydrocarbon?

Coal, petroleum, and natural gas all contain hydrocarbons by nature. Chemical molecules known as hydrocarbons solely include carbon and hydrogen. Crude oils are used to produce them from fossil fuels.

Hydrocarbons are compounds containing hydrogen and carbon. They are mainly formed from organic fossils. They are found under the earth surface. Crude oil also known as petroleum, coal and natural gas are rich in hydrocarbon compounds. Thus they act as natural sources of hydrocarbons.

Propane and butane are hydrocarbons that are utilised as heating and transportation fuels. In automotive engines, liquid hydrocarbons like gasoline are used. Lubricants made of large hydrocarbons are employed. For combustion, fuels like compressed and liquefied natural gas are employed. The production of polymers like polythene uses hydrocarbons.

Hence, the correct answer is option D.
