Assertion : F.hepatica undergoes both aerobic and anaerobic respiration. Reason : Fasciola respire only in absence of oxygenA. If both the assertion and the reason are true and the reason is a correct explanation of the assertionB. If both the assertion and reason are true but the reason is not a correct explanation of the assertionC. If the assertion is true but the reason is falseD. If both the assertion and reason are false

Answer» Correct Answer - C
F. hepatica undergoes both aerobic and anaerobic respiration depending on the availability of oxygen. Oxygen content in bile being extremely low, respiration in F. hepatica is anaerobic or anoxybiotic. This is an exothermic reaction involving release of energy (heat). If free oxygen is available, aerobic respiration takes place.
