Which of the following statements best compares nuclear power and hydropower based on their rates of renewal?
A. Hydropower has a faster rate because water is continuously being recycled through the hydrogeological cycle.
B. Nuclear power has a faster rate because all elements are spontaneously radioactive and are a source of nuclear energy.
C. Hydropower has a slower rate because a large volume of water vapor that evaporates takes several years to return to water cycle.
D. Nuclear power has a slower rate because the nuclear waste produced is not radioactive and thus cannot be used further as a fuel.
