Answer:
C. Wind Power
Step-by-step explanation:
Since the city experiences "high winds". Wind power is a clean source of energy, that is renewable.
The structure covers a small area and also leaves a low carbon footprint. This allows large areas to be used for agricultural purposes.
The river, I believe cannot be a suitable resource, for hydropower. Because in a rural community, the river is used for other purposes. And the Hydropower plant (HPP) would require exclusive use of the water.
For the same reason a nuclear power (NPP) plant and geothermal power plants (GPP) could not be ideal, because the river becomes polluted and not suitable for consumption of animals or humans.
