Final answer:
A nonrenewable energy source from the given options is C) Fossil fuel, which includes coal, oil, and natural gas that took millions of years to form and are being depleted faster than they can be naturally replenished.
Step-by-step explanation:
The nonrenewable energy source from the given options is C) Fossil fuel. Nonrenewable energy resources are natural resources that cannot be replaced as quickly as they are used up. Fossil fuels such as coal, oil, and natural gas are prime examples of nonrenewable resources. They formed from organic materials over the course of millions of years and we are consuming them at a much faster rate than they can be replaced. Renewable energy sources like solar power, wind power, and hydroelectric power are inexhaustible within the human timescale, as they are continuously available and replenished naturally. Fossil fuels currently dominate the world's energy consumption but contribute to global warming due to CO2 emissions. This underscores the importance of transitioning to renewable energy sources.
