Options

A. Coal
B. Petroleum
C. Wind
D. Peat

Explanation

To determine which form of energy is environmentally friendly, we need to analyze the options provided, which include coal, petroleum, and wind energy.

### Step-by-Step Solution:

1. **Identify the Energy Sources**: The question mentions coal, petroleum, and wind energy. We need to evaluate each of these sources in terms of their environmental impact.

2. **Understand Fossil Fuels**: Coal and petroleum are fossil fuels. They are formed from the remains of dead plants and animals that have been subjected to heat and pressure over millions of years.

3. **Environmental Impact of Fossil Fuels**: When fossil fuels like coal and petroleum are burned for energy, they release a significant amount of carbon dioxide (CO2) and other pollutants into the atmosphere. This contributes to air pollution and climate change, making them harmful to the environment.

4. **Evaluate Wind Energy**: Wind energy, on the other hand, is generated by harnessing the power of wind through turbines. It does not produce harmful emissions during operation and is considered a renewable energy source.

5. **Conclusion**: Based on the analysis, wind energy is the environmentally friendly option compared to coal and petroleum, which are harmful to the environment due to their emissions.

### Final Answer:
The environmentally friendly form of energy among the options provided is **wind energy**.
