3. Oceans and seas (accumulating on the seafloor).
Explanation:
Well-established researches have concluded that the fossil fuels that turn into hydrocarbons: coal, fuel oil, or natural gas, are formed from the dead plants and animals that were left for millions of years underground seafloors. Thereafter, the compounds that make up these planktons and plants turn into fossil fuels through a complex process of decomposition, during which they form peat and coal. Then, these resources are extracted through coal mining and the drilling of oil and gas wells onshore and offshore.
