Answer: The correct answer is C: production of greenhouse gases.

Explanation:

Due to hydropower dams use water (natural element) to generate electricity, they don't emit carbon dioxide/carbon monoxide to the atmosphere avoiding in that way the production of greenhouse gases. However, the use of hydropower dams can affect the environment in other ways. For instance, it causes water pollution, uprooting and trees damage, etc.
