Fossil fuels are non-renewable energy sources formed over millions of years from the anaerobic decomposition of buried organic matter. Common examples include coal, petroleum (crude oil), and natural gas. Petrol and Diesel are refined products derived from petroleum. Wood is a form of biomass and is considered a renewable fuel (if harvested sustainably). It is not a fossil fuel as it is derived from recently living organisms and is not formed through geological processes over deep time.

- 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:
