Solution:Concept: We must first comprehend what fossil fuels are in order to respond to this query. Decomposition of living things yields fossil fuels. These fuels, which contain carbon and hydrogen and are present in the Earth's crust, can be burned to produce energy. Coal, oil, and natural gas are a few examples of fossil fuels. By heating this substance, thick oil that can be used to make gasoline is created.
Natural gas, coal, and petroleum are a few examples of high carbon content fossil fuels. A couple of frequently used derivatives of fossil fuels are propane and kerosene. Fossil fuels are substances with low carbon-to-hydrogen ratios that are volatile (such as methane) , liquid (such as petroleum) , and nonvolatile (such as anthracite). Having read the information about how fossil fuels are formed above. It is clear that the fossil fuels were created from the earth's subterranean remains of dead plants and animals.
That comes from the remains of extinct plants or animals known as fossil fuel, or coal. Through a process called carbonation, coal is created over a period of millions of years. Under extremely high pressure and temperature, dead vegetation is transformed into coal that is rich in carbon in this process.
Hence, option 1 is correct.
