A bio-gas plant primarily produces biogas (methane and carbon dioxide) and digestate. The digestate is a nutrient-rich residue that can be processed into solid and liquid fertilizers. Biogas can be upgraded to Bio-CNG by removing carbon dioxide and other impurities. Some integrated waste management systems might also incorporate vermicomposting to further process organic waste or digestate, which would produce vermiwash.
At Banas Bio-Gas Plant, the end products produced include 1. Bio CNG 2. Solid fertilizer 3. Liquid fertilizer 4. Vermiwash Select the correct answer using the code given below:

- 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:
