Which option correctly identifies the two main categories of energy sources mentioned?

• A. Solar and wind
• B. Fossil and renewable
• C. Renewable and non-renewable
• D. Kinetic and potential

Answer: (C)

Energy sources are categorized by whether they can be replenished in a short time. Renewable sources come from natural processes that continually replenish themselves, like sunlight, wind, and flowing water. Non-renewable sources are finite and form over geological time, so they can’t be replenished quickly once used, such as fossil fuels. The pair that includes renewable and non-renewable best captures this broad distinction for all energy sources. The other options point to specific examples, mix one renewable with a non-renewable, or refer to forms of energy rather than sources.
