Final Answer:
Two examples of different fossil fuels currently used today are A) Coal and natural gas
Step-by-step explanation:
Fossil fuels are hydrocarbons, primarily coal, fuel oil, or natural gas, formed from the remains of dead plants and animals. They are currently used as significant sources of energy worldwide.
Coal: This is a solid fossil fuel formed from plant remains. It is burned to generate electricity and is a major source of energy in many countries.
Natural Gas: Comprising mainly methane, natural gas is a fossil fuel extracted from underground reservoirs. It is used for heating, electricity generation, and as a fuel for vehicles.
Option A, "Coal and natural gas," correctly identifies two examples of fossil fuels commonly used today for various energy purposes.
