Answer: (D)

Verified step by step guidance

1. Understand the definition of renewable and non-renewable energy sources. Renewable energy sources are those that can be replenished naturally in a short period of time, while non-renewable sources exist in finite amounts and take millions of years to form.
2. Identify the energy sources listed: Coal, Oil, Natural gas, and Wind. Coal, oil, and natural gas are fossil fuels formed from ancient organic matter over millions of years, making them non-renewable.
3. Recognize that wind energy is generated by natural atmospheric processes and is continuously available, making it a renewable energy source.
4. Compare the characteristics of each energy source to determine which fits the renewable criteria: wind energy is sustainable and does not deplete over time, unlike fossil fuels.
5. Conclude that among the options given, wind is the renewable source of energy because it is naturally replenished and environmentally sustainable.
