The correct option is (a) Biogas

The best I can explain: Biogas can be used as a source of energy which is produced at the end of anaerobic fermentation, Alcohol and Amino acid are produced earlier in the fermentation process. Toxic products are eliminated from the process pre-composting to avoid accumulation in the later processes.
