Answer» Right option is (d) 8 The explanation is: The COMPLETE anaerobic digestion of cow manure takes about 8 weeks at normally warm temperatures. ONE third of the total BIOGAS will be produced in the first week, another quarter in the second week and the remainder of the biogas production will be spread over the remaining 6 weeks.
