(A)A-Methanogenic bacteria, B-Fermentative microbes, C-CO2 and hydrogen (biogas)
(B)A-Anaerobic microorganisms, B-Methanococcus, C-CO2 and nitrogen (biogas)
(C)A-Fermentative microbes, B-Methanogenic bacteria, C-CO2 and methane (biogas)Correct
(D)A-Aerobic microorganisms, B-Methanobacter, C-CO2 and methane (biogas)

Answer: (C)
