Renewable energy sources are those that are replenished naturally on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Wind energy, solar energy (from sunlight), and biofuels (derived from biomass that can be regrown) are examples of renewable energy sources. Nuclear minerals, such as uranium, are finite resources extracted from the Earth's crust and are consumed in nuclear fission reactions to produce energy, making nuclear power (based on fission) a non-renewable source.

- Below are given two statements, one labelled as Assertion (A) and the other as Reason (R). Assertion (A): Biogas has a very high proportion of methane which can be used as fuel for various purposes. Because it does not release smoke or residue, it should be considered a good and safe source of energy. Reason (R): Biogas also contains carbon dioxide. Due to the high proportion of carbon dioxide, biogas gives low energy compared to natural gas. In the context of the above statements, choose the most appropriate answer from the options given below:
