Which of the following best describes a renewable energy source?

A renewable energy source is characterized by its ability to regenerate naturally over time, making option B the most accurate description. This includes sources such as solar, wind, hydroelectric, and biomass energy, all of which can be replenished naturally and sustainably. For instance, sunlight is constantly available, wind patterns are continually generating energy, and water cycles lead to ongoing hydroelectric power generation.

In contrast, the other options fall short in defining renewable energy accurately. A source that can be depleted quickly does not align with the fundamental nature of renewable resources, which are meant to be sustainable and available over the long term. A source only usable during certain seasons would not meet the criteria for consistency in availability that typically defines renewable energy sources. Lastly, a source generated from fossil fuels is inherently non-renewable, as it involves the consumption of resources that cannot be replenished within a human time scale, which contradicts the principles of renewability.
