Which of the following is renewable energy?

Explanation:
Renewable energy comes from sources that naturally replenish on human timescales. Water energy uses the flow and fall of water to spin turbines, and water continually cycles through the environment via precipitation, rivers, and oceans. Because the water cycle keeps replenishing usable water, hydropower can be tapped repeatedly without running out in our lifetimes. In contrast, coal and oil are fossil fuels formed over millions of years and finite in quantity, and nuclear relies on fuels like uranium that are not replenished quickly. So water energy is the renewable option.
