Assertion : F.hepatica undergoes both aerobic and anaerobic respiration.
Reason : Fasciola respire only in absence of oxygen

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer

C

Explanation

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.
