Answer:
Hazardous to birds, vibrations cause structural problems, and noise and visual pollution.
Step-by-step explanation:
Wind power is used as the renewable source of the energy and reduced the dependence of human beings on the fossil fuels. The wind turbines and the electric generator is used for the energy production.
The production of the energy requires the wind turbine construction. This will result in the release of the harmful radiation that might affects the birds. The vibration and radiations release are so harmful that might cause visual problems and vibration detected by the birds can cause hearing problem and noise pollution.
Thus, the correct answer is option (c).
