Answer:
Option C
Explanation:
The situation of fatigue occurs in an athlete when he/she is doing rigorous exercise or an activity requiring intense muscular activity. In these scenarios, muscles cells undergo anaerobic respiration which eventually leads to acidification and hence fatigue in muscles. Also during this scenario, the resting membrane potential of the muscles depolarizes and muscle may deplete in severe cases. Thus, during temporary fatigue muscle experiences highest level of anaerobic respiration.
Option C is correct
