Answer :
The nonrenewable source of energy among the options given is oil.
1. Oil is a fossil fuel that is formed from the remains of ancient plants and animals over millions of years. Once extracted and burned for energy, it cannot be easily replaced or renewed in a short period of time like renewable sources such as wind or solar energy.
2. Geothermal energy, on the other hand, is a renewable source that utilizes heat from the Earth's core and is considered environmentally friendly and sustainable.
3. Wind and solar energy are also renewable sources that rely on natural processes like wind movement and sunlight to generate power without depleting finite resources.
Therefore, out of the options provided, oil is the nonrenewable source of energy.
